The quantity in the product is always unlimited after saving

Hello,
I noticed today that all my products have lost their quantity settings and are all showing as ‘unlimited’ for the quantity.
If I change ‘unlimited’ to a specific number in a product, it goes back to showing ‘unlimited’ after I save it.
