Page for Testing (required) - No eligible pages

Hi,

I can't put it in words how upset Im. Im trying to submit my permission request to Facebook for 2 days now. I wasted a lot time.
They asking tons of screenshots of nothing. How can an user like a page. etc.. I just don't understand who had the time to figure out these requirements and I found basically zero tutorial or explanation or anything. Very annoying.
It seems to me that I have one thing left.
"Page for Testing". To be honest I don't even know what they want from me and there is also noting to help or give some clue.
As far as I know JFBconnect sets up my Page App. It is set however I can't choose it and the drop down menu remains grey. Who knows why.
Does anyone can help me what is wrong here? Why I can't select my Page for testing?
Here I attached 2 screenshots:

Many thanks
