 ### Fixed
 
+- We fixed an issue where clicking the group expansion pane/arrow caused the node to be selected, when it should just expand/detract the node - [#10111](https://github.com/JabRef/jabref/pull/10111)
 - We fixed an issue where the browser import would add ' characters before the BibTeX entry on Linux. [#9588](https://github.com/JabRef/jabref/issues/9588)
 - We fixed an issue where searching for a specific term with the DOAB fetcher lead to an exception. [#9571](https://github.com/JabRef/jabref/issues/9571)
 - We fixed an issue where the "Import" -> "Library to import to" did not show the correct library name if two opened libraries had the same suffix. [#9567](https://github.com/JabRef/jabref/issues/9567)
