Model Release for Display Dummy? *lol*

Hallo,

I have a problem. I can not post an image with my "Doll" (Schaufensterpuppe / Display Dummy) without a "Model Release Contract"?

Model Contract with a Doll... *lol*? Right keywords are not helping? Are there only Robots by Adobe Stock German?

German Adobe Stock Support-Contact = Zero!

Can anybody help for this problem? Adobe Stock Support Germany-Contact Mail?
