Is this right? Having problems getting the proper percentages for exactly a min raise and nothing bigger

(Raised Flop 2bet(first flop raise)) AND (Flop 2bet size percentage of pot between 50 and 80)

The size of a min-raise has nothing to do with the size of the pot - it's only related to the size of the bet, so that type of filter won't give you what you describe. There isn't a filter for raise size relative to the bet size so I don't think you can currently filter for min-raises like that.

Ok cool i have another one i was wondering about. A note for when they call a turn and river bet with bottom or underpair to the board after the flop was checked through, is this possible?

Yes, you should be able to do that. Use 'Hand Values' to set the hand strength.
For the flop being checked through you can use Actions and Opportunities > Flop > Action Sequence. Set the first action to 'check' and the second action to 'any', and then 'NOT' the second action (you'll need to add them separately so that you can 'NOT' just one of them).
