Update button disapeared

Hello,

Since I’ve updated UAM to 1.2.6.0, the “Update” button has disapeared when I edit a published post. The button “Publish” always replaces it.
Besides, the state of posts can’t be changed in “editing mode” (for Published to Draft for instance). It only works with quick editing mode.

The problem is still here with 1.2.6.2.
And I had this bug on WP 3.5.1, and now on 4.1.1 that I’ve updated today.

I’ve deleted the cache of my browser and of WordPress, but nothing changed.

Thank you for your help or for a quick fix.

Best regards
