Welcome aboard to the Community, @serdar.karadayi.
We want to lend a hand with your concern about deleting and adding purchase VAT rates. However, we need to know more about it to provide the right resolution and to get this fixed as soon as possible.
Can you share with us how you create them in QuickBooks? Any details you can add to your response will help ensure a timely solution on this.

Drop me a comment below if you have any other questions. I'll be more than happy to help. Wishing you a good one.
