Amazon MBA Designs did not show up

Hi guys,

i bought a few (actually a few more ) designs and try to sell them at spreadshirts, redbubble etc...
Though my main goal is to sell them on MBA America/great britain and germany.

So in the last weeks I uploaded my designs and they went LIVE. But if I search them on amzn i cannot find my shirts. Even if I search for the absolute exact title e.g. (Valentine Love Couple Tshirt) I cannot find my Shirt?!

Whats wrong here? Any ideas?

Thank you for your help

Maybe they need some time to setup
