XF 2.2 User Upgrade won’t work after payment

[Tempritscher]

Greetings Community
Im currently facing an issue which I’m unable to fix till this day.
After a user upgraded his account with an one time payment or monthly subscription, the rank won’t change automatically.
I never had issues in the past. I also saw some people here having the same issue.
Maybe someone has a solution for me.

Here is the latest payment log:
array(17) {
