Looks like "Checked Flop" filter doesnt work foe multi way situations. There are some hands with flop action: check, check, bet...

That filter is specific to the active player and means that they checked the flop and this will include checks, check calls, check folds and check raises. If you want to filter for the flop getting checked through then you can add a NOT filter for calling/raising/folding on the flop.
