There is no need to cross post in multiple forums, you’ll be wasting other users time if they try to help you in one when you have solved your problem in the other.
You have a response in your other thread so stick with that even though you don’t describe what “weird” means with either a screenshot or blend file.
Also the usual response is for the poster to ask for the duplicate thread to be deleted, don’t bother as it won’t be even if you ask.
