Change level of multiple bullet points

I have a Document wich is structured with bullet points. I tried to restructure it. Multiple points needs to leveled up (from second level to first level, third level to second). I tried it with Shift + Tab.

If I mark from top to bottom it never Works. When I mark from bottom to top it sometimes works. Is this a bug or do i sth. wrong?

System Informations:

  • Libre Writer 5.1.6.2
  • Build-ID: 1:5.1.6~rc2-0ubuntu1~xenial1
  • CPU-Threads: 4; BS-Version: Linux 4.4;
  • UI-Render: Standard;
  • Gebietsschema: de-DE (de_DE.UTF-8); Calc: group
  • OS: Linux Mint

If the items belong to the same item of the next higher level, then you shift only the higher level item. The list toolbar has a symbol to decrease level including all subitems.

If you do it with Tab or Shift+Tab, take care that the cursor is located just before the first character of the paragraph, i.e. between the bullet and the first character.
