Example with many styles - mark a style and have a look at the sidebar.
Following bug appears with some special documents, here all chapters of Base-Handbook. I have added one chapter as attachment.
Open the attached file.
Move the cursor a little bit down to some text.
Mark a heading.
The style will be changed at the listbox on the left, but won't be changed by the paragraph styles in the sidebar.
Click with the mouse to other styles - the same behavior: No changing in the sidebar, only changing in the listbox.

Difference in styles between sidebar, document and listbox.
Under Kubuntu the sidebar the change is visible only after 10 seconds.
Hello Robert, *,
I can confirm it with your attached document with LO
Gebietsschema: de-DE (de_DE.UTF-8)
(parallel installed, following the instructions from https://wiki.documentfoundation.org/Installing_in_parallel/Linux) under Debian Testing AMD64. Interestingly, I cannot confirm it with https://wiki.documentfoundation.org/images/1/15/Base_Gesamtband_einseitig_V50.odt (your complete guide) nor with LO
Bug disappears. Couldn't be reproduced any more with LO 5.0.5, also LO 5.1.1
I will set this one as "Worksforme"
