devices working great but not working with scenes

Hey there ,
I have a vera edge controller.
at some point I had 8 fibaro rollers and 8 fibaro double relays (for lights).
everything was working flawlessly with many different scenes.

2 days ago there were 2 changes :

  1. I added 2 fibaro motion sensor and 1 fibaro flood sensor.
  2. I’ve upgraded vera firmware to the latest (up until then I was one version before latest)

ever since , all scenes that involves changing rollers shutters position don’t work.
a roller or 2 can work sporadically but not all the rollers work.
if I try controlling each one of the rollers individually they all work.

I’ve tried to stick a USB with memory card in order to get the logs but I keep getting this error when trying to enable logs :

Installing required kernel modules and apps… FAILED

Can anyone help with this issue please?
