Seat Reservation Failed

Hello!

i've recently created a new facility, and was testing my "best seating" setup. I have some sections that throw the following error when trying to best seat:  "Seat Reservation Failed: Could not find seats for specified criteria."

I can select these seats from the client, just not when best seating. I've checked the "validate completeness" feature, and it all came back clear. What am I missing??

Thanks,

Lesley
