Seat Count Oddities

I'm building out widgets to look at our animal Encounter programs. One of the metrics we're looking at is Total Sold Seats vs Total Available Seats. The numbers appear correct for each program, except one.

This program has one seat available per performance, three performances per day, for the rest of the year (starting 10.8.20, through 12.31.20). Pulling information from the number of performances through Season Maintenance, it returns a total of 249 performances, and therefore 249 seats (the rest are blackout-held).

However, Analytics for a few days has returned a total of 717 total seats available. Even dividing 717 by 3 yields 239, not 249.

I've switched it from 'Sum' to 'Auto' for calculation, which doesn't change the total. I used a bit of bucketing to have it only look at seats with status = available, and that reduced the number to 714.

Why is it returning such a large number?
