PNG lost from MoGRT in Rush

I created a simple MoGRT in Premiere Pro with a bakground object color, a line of tekst and a logo in PNG. On my phone I used this MoGRT in a Sequence. When I open the synced Sequence on my PC the PNG logo is lost, leaving a dark red rectangle with a white questionmark in it. I don´t understand how the filesync fails here. I try to create the MoGRT with a different name on the PNG, shorter name, name without space. Nothing works. Why can´t it sync correctly from phone to PC with the logo? If I put in the MoGRT on my PC it works fine with the logo and all. But I need the option to start a sequence on the phone, and continue the work on the PC. Have the same issue with other MoGRTs loosing their PNG.

This one´s synced from the phone:

This one I put in the MoGRT on the PC. Same one from the Adobe CC library:
