bonus balance duplicated

Logged in after a break and my bonus balance was literally showing double what it should have been, but my cash balance didn’t budge. Thought it was some magic glitch and had visions of the slot machine gods finally rewarding my years of charitable deposit activity. Did a quick test spin on my go-to fruity slot and the bonus didn’t decrease the right way - it looked like half my bet came from each version of the bonus. Not complaining exactly, but something isn’t adding up and now I’m not sure if I’m gonna get paid if I actually hit something good.

Has anyone run into a bonus system glitch like this where the numbers look inflated but nothing else changes? I’m itching to fire up a blackjack session but don’t really want to be stuck with phantom money or get locked out mid-way through a lucky streak. Just feels a bit sketchy to play with a balance I can’t trust, even if it’s funny to look at that number for a second.
