Pb with studio

Hello , i have a problem with studio to erase "hide if " condition like on the characteritics panel ( meetingAttributesPanel ) . I delete the condition , save . I Check Hidden , when i refresh the studio , the condition ( typeSelect == 5) is not delete and the hidden activate . This condition can be deleted .

Do you have the same problem , i have this problem many times , perhaps a bad manipulation
Regards
