At the first request and if nothing is changed - everything is fine.
But if you want to change appearance PROFITS screen and press "B" or "T", the screen becomes clean and no longer returns to its original state, whatever you press. The other tabs work fine.
UPD:
Pressing "T" does not lead to any changes - the output results are the same (previously a huge list was issued). But pressing "B" erases the screen.
