rakeback credited wrong

so i noticed my rakeback wasn’t matching what i calculated for this week. usually it’s right on, maybe a little off here and there, but this time it’s just way under what i should’ve gotten. i track every session and double checked my numbers, even scrolled back through my hand histories to be sure. not talking a few cents either, more like 10-15% lower, which definitely adds up over time. i play mostly mid-stakes cash if that matters, and no bonuses were running that would eat into it as far as i can tell.

has anyone else had this kind of thing before, where the rakeback just gets credited wrong out of nowhere? did you have any luck getting it fixed or did they just blow you off? not sure if i should reach out or if i’m missing something obvious in the calculation. thoughts?
