I see the issue has been resolved here, but my issue seems similar, might be related. https://github.com/abpframework/abp/issues/21185
Updated from 8.1 to 9.1.1 When i go to ABP-s default pages, lets say "users" or "Languages", and then i move back to my custom pages/homepage, the title stays visible that are inside the lpx-content-toolbar. The buttons dissapear as they should when switching pages.
I tried updating to 9.2-rc-2 but it also did not help.
