Perfect pairs cap?

Anybody got a clear answer on if there's a usual cap on payouts for perfect pairs? Been hopping between a couple crypto tables and I keep running into random limits. Sometimes it pays out normal up to like 250, sometimes I get told I hit a “max win” and the rest just gets voided. Weird thing is the main blackjack win doesn’t seem to have the same cap or it’s just higher.

It messes with the way I prioritize my side bet stakes since there’s no obvious pattern. I know some places cap any side bet to prevent a massive hit, but if the main game lets you win more, it just feels like the side bets get nerfed way harder than necessary. I could just be overthinking this but if anyone’s tracked the caps or noticed a logic, throw some details in here. The risk management on these tables is way more aggressive than I’d expect for such a low-frequency hit.
