The tail gate still has no 'ubdichtung'
Check if anything is forcing the weather strip up; if not try using a heat gun to let it relax and settle down.

Update.

Today is the first time I have had my truck in the rain. The hing area on the last panel before it shuts is leaking pretty good. I sent Moorie an email to get a warranty claim started.
I will chime in and let you guys know how it goes.
