Created attachment 117620 [details] 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.
Created attachment 117621 [details] 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 Version: 5.0.0.5 Build-ID: 437e4abdf9e72fd0a6e6f8697a0e659bc77f9b10 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 Version: 4.4.4.3 Build-ID: 40m0(Build:3) Gebietsschema: de_DE.UTF-8 (Debian's version). HTH Thomas.
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"
