Reply To: The presence filter and the size filter in combination do not work correctly

1. You need to increase the AJAX variation threshold option in Theme Settings > Shop > Variable products https://prnt.sc/hexB8bkQ3C2s to the number of variations in the product and +1.

I increased the value from 79 to 80

2. Re-assign each variations https://prnt.sc/PWTBNeCyiu4V

I don’t understand how it is to “re-assign variations”? Can you describe it in detail? The product is not available in our warehouse, how could you add it to the cart?
