Product Variation Not Found! Place Order Function

The place order function seems to be broken. It pops up and says variation not found, Then it asks me to select the variation, When I choose the variation, and click proceed, it again tells me variation not found. I've already placed one order manually. But now it wont pull the tracking info. I'd like to fix this.... But they should ad a place on the order invoice to add your aliexpress order ID so it can still pull the tracking info, if something like this happens again.

Any suggestions on how to fix this.

Edit: the variation is available and can be selected but its still reporting its not available.
