Spots available not matching up with how many open squad positions?

I have a match that has 137 slots open (including 17 reserved spots) But for some reason, practiscore is only showing 120 spots initially available? Match already has less than “100” available, but there should be more… Will this self correct? I havent seen this before

Without having the exact name of the match where I can’t tell you for sure. But most likely what is happening is that when you reserve 17 slots those slots are not shown as available to registrants.
Therefore a 137 person match would show with 120 slots available.
