Campaign only playing once complete

Hello Team,
first: latest CMS via Docker, latest Android client on DSCS9

I have a campaign and an overlay layout. All of the layouts are playing well when I play them solo. No errors. Once I use the campaign, it plays all the layouts of it once and then it stucks to one of the layout in loop. and it’s not the first one in the campaign. I get an error in the Androiud client: Blacklist [splash.png] Unsupportetd Image. Unable to decode.
But I don’t use a file with this name.

I removed all background jpgs that I used in my different layouts. I is still only playing once (after restart), but I now have other messages.

Can anyone tell my what “Skipping validity check on current layout” means?

ok. Final test experience: I have a layout with the new iCal module. When I schedule it solo, it works. When I schedule it in a campaign, it won’t work.

It’s the splash screen image that comes with Xibo for Android, rather odd that it would get blacklisted though.

Is your CMS available over the internet? If so i could have a quick look for you, if you can share the login credentials with me via private message.

I send you a pm.
But the blacklist was gone when I removed all background pictures. But the one layout is still now playing as a part of the campaign.

ok, some new information:
I just tested it with another layout which is basically the same but without iCal. The date there comes from a DataSet. This is working. So there must be something with the iCal module that blocks the scheduling.
