Unfortunately I think you found yourself in situations where your hand was “too good.” Nothing you can do. You need someone to show up with some kind of calling equity on danger boards and these guys just didn’t have it this time. If your 3-bet range is really tight, they might just be calling pre-flop knowing they have to out-flop you and, if they don’t, they know they’re auto-folding. Tough to tell without knowing your 3-bet range pre-flop.
