Transmission Pressure

Hey Y'all, got a little issue with my 11 f350 6.7 (deleted and tuned). Had the trans replaced at about 60k to the BD upstage. Recently I have noticed that after a good workday of pulling or after getting on it the trans dipstick pops out. No fluid leakage from under hood. I do have the pressure box added. Is this normal (I am guessing not) and what would be causing the dipstick to pop out of tube. Is there a vent line that i am missing that might be clogged? any information would be greatly appreciated. Thanks in advance

There is a vent at the top front, right where the case transitions from bell housing to flat-ish. I'd probably start by changing the o-ring on the dipstick ~~tube~~ though.
