I reported this bug back in February 2019 in the thread: viewtopic.php?f=19&t=9282
Well, for the last several months now I have kept updated with using the latest x64 donor versions (currently 819), and I still constantly - that means *all day every day* - experience this bug.
I commonly have 5 tabs open in the left pane, and maybe 10 in the right pane. In the right pane I navigate in an existing tab to the folder an item should go, then move an item from the left pane to the right pane (using the red move button between the panes), and then I double-click "..." folder to go back up a level or two or I click on the button to go up a level or however many, or I click on a favorite folder to return to, and, after doing so, the name on the tab does not update to the new folder. The pane shows the correct folder and its contents, but the name on the tab is still showing the old folder.
Unfortunately, I am not able to give more steps than above to help identify or reproduce the bug, but, again, this bug has persisted for well over a year, not just in the public versions but still exists in donor x64 819 (which is what I am using today on Win 10 x64 v1903)
Thanks, and feel free to contact me for more info or with instructions on how to retrieve information that may be helpful in squashing this long-lasting bug! cheers
