My Extension is set to incomplete, why?

I tried to upload my new extension version
https://addons.mozilla.org/de/developers/addon/typo3-workbench

Info says “TYPO3 Workbench version 1.7.0 rejected.” But on the upload site it says “all tests passed”.
Overview says “has been disabled by Mozilla”
Also the addon is “Incomplete”.
But I can`t figure out whats wrong. No infos, what to fix or change, nothing.
Can someone from the AMO team giv me a hint? Please!
Kind regards
Markus
