There are a few key stylistic changes which might solve the paragraph display problem.
It always helps to display invisible characters: the menu item to toggle that is
Nonprinting Characters. Then, do you see paragraph marks between the paragraphs, or do you see page break marks? If you see the latter, then it probably means that all paragraphs have a page break as part of their applied style.
Now, the question becomes: has styling been applied consistently? If formatting has been applied manually and by multiple people, then probably not. However, most paragraphs should have the same base style, either Default, Body text, Normal or something like that. In order to know which style is applied to a paragraph, first display the Styles and formatting window by toggling the menu item
Styles and Formatting. You can anchor this window to the side (I highly recommend doing so and developing a habit of using it for literally every formatting-related task). Now, when you put the text cursor in a paragraph, that paragraph’s style will be highlighted in the Styles and Formatting window. This allows you to know which style you need to change.
Right-click the appropriate style’s name, then click
Modify…. In the dialog box, go to the
Text flow tab. There, under the Breaks heading, if the Insert box is checked, you have found the culprit. Uncheck the box and all paragraphs with this base style should now display normally, with natural breaks occurring at the bottom of the pages’ display areas.
Keep in mind that paragraphs might have manual formatting applied on top of the base style. If that is the case, even unchecking the break box in the style will not remove breaks if breaks were applied manually (Microsoft Word does such ridiculous things all the time, so it would not be surprising). The radical solution is to select all such paragraphs and choose the menu item
Clear Direct Formatting. This is a good cure. If any other manual formatting was applied, it will be lost as well, but in any case the formatting should always be applied by creating named styles in the Styles and Formatting window.
Hope this helps!
