Dark Light Button freezes Zotero's theme changing

[rafisics]

I am using Zotero 7 in Ubuntu 24.04 LTS. Initially, Zotero's theme was nicely changing accordingly with the system's dark/light style. After installing the Zotero Style plugin, I once clicked its Dark Light Button. Since then, Zotero's theme seems to be frozen. It is no longer changing with my system's dark/light mode. I tried to fix it by disabling the plugin, uninstalling the plugin, and also with the Troubleshooting Mode.

What is causing this issue? How can I get back to the default behavior of the Zotero theme?

Silly that I didn't notice that I could resolve the issue simply by going to Edit > Settings > General > Color Scheme and choosing the option automatic.
