Keyword Tag Search Problem

I have just uninstalled digiKam; and, when I went digging into the various nooks and crannies to delete any remaining traces, I found these two files lurking in my AppData Local folder:

digiKam_tagsmanagerrc and digiKamrc

Could this digiKam_tagsmanagerrc file be the reason why, even though I would delete the thumbnail database and even rebuild the main database, my Tags View problem would always remain with me ?

Of course, I can’t play around with it now, as it has been uninstalled, but I would be curious to know if maybe this could have been the culprit.
