Page inserting itself after paragraph AND after footnote superscript even followed by a word

A drop-down to the next page or a blank page is inserting itself after a paragraph, as well as after an inserted footnote (the superscript number) even when there is a word in the same sentence inserted after the footnote number in the main text-body.

I have read the manual and used Libre Office extensively – but cannot overcome this problem unless I go through paragraph by paragraph and back-space between and then re-enter the 0.5 indentation each paragraph. AND I have to do the same after a footnote superscript is inserted.

THEN the footnote style has a 12-point number in the footnote area itself, and this causes the 10-point font of the footnote message to drop down, often several lines, also shortening the text in the main body of the page above.

No matter how many times I correct these annoying blanks, I canNOT prevent them happening again in the same document. FURTHERMORE, I canNOT get the DEFAULT STYLE to change to the ONE I USE!

I have searched all these topics and do not find these problems – ARE THEY BUGS?

Please verify if there is a page break for the paragraph style.

Menu/Format/Paragraph - [Text flow] - Break - Insert.

Thanks for the suggestion; here is the result:
In order to set TEXT FLOW under Format> paragraph, to “keep with next paragraph” – I had to select the entire document (more than 200 pages). All the footnotes that occur in the middle of a sentence and therefore mid-paragraph, remained as new paragraphs. All the INSERT > manual >new page before ALL CHAPTERS then were wiped out. I can’t find the way to edit the FOOTNOTE–TEXT BODY interacting style, nor the text within footnote.

I HAVE BEEN USING THESE 2 HELP TOPICS – BUT THESE PROBLEMS ARE SO BAD I CAN ONLY THINK OF IT AS A SERIOUS BUG IN LO, because you canNOT get to the TEMPLATE STYLE you want in the first place to SAVE AS TEMPLATE! The spaces show up only after you’ve saved your document, not while you’re writing it, so they too would be “saved as template.”

Changing Default Templates
When you open a new document with File - New, a blank document appears based on a LibreOffice template. You can edit, modify, or replace this template so that the new document contains your customized Styles or other contents.
Modifying Default Templates
First, open either an existing LibreOffice template and modify it, or open a new document and edit it as necessary to create the desired template.

You can define a document template for each LibreOffice module. The following describes how to proceed for text documents.

  1. Save the document by choosing File - Save As Templateand saving the document in the My Templates category.
  2. Choose File - New - Templates.
  3. Double-click My Templates in the list. You will see the user-defined templates in the user directory specified under LibreOffice - Preferences - LibreOffice - Paths. Select the template you have just saved.
  4. Choose Set as default. The next time you open a new text document, the new document will be based on the new default template.

Using Custom Templates
There are several ways to make your work easier by using your own custom templates.
Templates in the Template Folder
You can save a new template with File - Save As Template or by selecting “Template” file type in any Save dialog. Save the template in the user directory specified under LibreOffice - Preferences - LibreOffice - Paths to be able to access the template from within the File - New - Templates dialog.
To open the template for editing, choose File - New - Templates, select the template and click the Edit button.
