Mixamo Store in Unity Tag Price (Minus) - ??

Hi
I try to buy Mixamo animation via the Mixamo Store in Unity this week. I was unable to purchase my transaction. Unity support told me that everything was fine on their side. So after some investigation I saw that the price tag on every animation was in the negative. Ex: -10.00$ So my total amount was for example -15.00$ I Add another asset from another company at 5.00$ So my total amount was now -10.00$ !!! : shock: I send an email to Mixamo support to check that out but no reply for now.
I am posting here just in case if someone else had the same problem.

Thanks
