Seems to be both pre flop and post flop. It happens in only multiway pots. It is in the replayer.
When the street starts. It calculates all percentages. This is how to should be. When one has folded, it should no longer include the folded cards equity in the percentage calculation. It does not change untill the next street. As soon as one hand is folded, the folded hands equity should no longer affect the percentages.
