"Performance Sold Out Message" Not Triggering on Calendar/Listing Page

Hi, all,

I set up our classes on TNEW so that once they get full, the Event Link Detail Text ("Purchase") switches over to the Performance Sold Out Message ("Class Full - Join Waiting List"), as well as setting the "Limited Seating!" message to appear when five seats or fewer remain in the class. I've had this set up in the Product Type Editor for anything with the Education type, and it has always worked until this season. Multiple classes have sold out, and the link continues to say "Purchase" instead of switching over. Any idea what might be happening or how I can fix this?

The class knows it's sold out. If you click the "Purchase" link, you see our custom Sold Out message/link (Please email _____ to be added to the waiting list.) instead of the drop menu for selecting seats. The only issue seems to be that the Event Link Detail Text won't switch over to either the Performance Limited Availability Message or the Performance Sold Out Text.

For the time being, I have manually changed the Event Detail Link to say "Class Full - Join Waiting List", but that can be a nightmare to keep up with when we have gobs of classes, camps, and workshops happening around the same time.

Some notes that might be important:

• I have checked the documentation to see if I'm missing anything, and Performance Availability Messaging IS enabled in the Page Editor. All seats in each class are either seated/paid/printed or have holds on them. 
• This is happening for classes that are in different Productions and Production Seasons.
• In case it was an issue with the Product Type Editor, I also changed the text at the performance level in the Product Editor and it still wouldn't change on the website, even after clearing the cache a few times.
• I've been building classes for years, and haven't done anything this season that I haven't done in past seasons, and I don't think I've encountered this issue before.

I cannot figure out why this one change is not happening. Any advice is appreciated.
