What should I do if V5 shows "Minimum order quantities cannot be duplicated within the same price category" when setting pricing tiers?

1. Check the "MOQ" for each tier within the same price category. Minimum order quantities must not be duplicated. 2. Click "Edit" in the upper-right corner of the product page and change the duplicate MOQs to different values. 3. After this operation was blocked, the original pricing tiers remained unchanged: MOQ 100 with a price of 10, and MOQ 500 with a price of 8.
