bug: i open artist view and choose one artist (actually in my case untitled artist) and open appearences. there are few albums. via 3 dots i open tag editor for one album. after editing click OK, in window i see that is working, after that it tells me that it is done and editor window is closed. and now im back in appearances but view is empty, no other albums visible. click to any other view (labels) and then back to artist and in appearances are back all albums without that one edited.
Issue reproduced, thanks for the report.
