Table min bug?

Anyone notice tables suddenly letting you place less than the posted minimum? Tried a $10 blackjack table earlier, just for the heck of it put $5 and it went through, no error or anything from the dealer. I did it again for a couple hands just to see if it was a one-off. Never seen it before. I know sometimes if you have leftover chips from a split or double, you might get weird amounts, but this was straight up less than the min from the start.

Now I’m debating if I should keep trying this for tiny hands or just avoid the table so I don’t get my balance locked for “abusing” something buggy. Wondering if anyone’s had the same thing or if this just happened to me.
