AME won't render the whole queue

Hi there,

i'm stuck with the following issue:

I want AME to encode proxies. After I selected the clips in PP and imported them into AME they show up in the queue as they should.
Everything works like it should - only problem: AME renders out the first file and then just stops. This way i would have to select each file of the queue one after another to let AME encode them. I just want it to encode the whole queue..

I am not a very advanced user of AME, maybe someone knows what's wrong for me? I am using Premiere Pro CC2017 and the Media Encoder CC 2017.

Help would be so great! Thanks!
