Superstore is the theme I am using. http://www.aldentecolorado.com is the website if you want to check it out. Click on Events and that’s where people can click on a class and add the number of events in the class. The adding to the inventory doesn’t happen on every time someone purchases a ticket, it seems random. The last time it did it was when I had 8 spots filled out of 12 and when the 9th was purchased, it added another class spot in the inventory so it said we had 9/13. So it was still allowing for four more class spaces when it really should have said 9/12. Have you gotten any other inquires about this? I have to manually add it. One time my class over booked by two spaces because of this problem.
