Removing redundancy

Hello,
since I'm encountering to much issues with the redundancy system and don't have the time to debug further, I decided to delete the secondairy node (for ex. the last restart the redundancy looked OK, but both all the plc's were out of sync resulting 2 same loads doing the same but with other values).
I hoped this was as easy as implementing the redundancy, so did the reverse order. Eventually the main node started, everything again looked OK, but the op station didn't want to mount the main node.
In the log file of the main node I found the following:
 

I removed the mounting, build with force and added back the mount but the problem remains.
One thing to note: all the builds were done with force.
Is it possible that there 's still flying around from the redundancy and messing things up?!?

In the meantime I restored back the old load backup and without any change the PLC's are nog in sync. But as stated above, I can change any moment ...
