Afrer making a fresh installation of Thunderbird all newly coming messages are visible only under "All" ["Wszystkie/PL] folder and not "Inbox" anymore. I tried to review existing filter, visibility settings and folder settings however can't see anything what it could be the cause of this issue. I would expect as before re-installing Thunderbid that all newly messages lands by default under "Inbox" folder and only those for wich I have configured filter rules are moved into specific folders that previously created.

Thank You.
