[112] Custom project not stable with retest Cross Checks blocks - CRITICAL

When trying to configure a new Retest Block (Custom Project) that includes a Cross Check, the Cross Check configuration is not stable.
It doesn't allow me to configure the MC trades manipulation and then click "Save":
   - Sometimes "Save" button doesn't work.
   - Sometimes even working it doesn't take the right configuration but the last one made.
   - Sometimes doesn't take into account any field modification.


It's an erratic behaviour that doesn't guarantee the right configuration at all.
It's not easy to replicate some times it happens and some tiems it doesn't.


Once everything seems right, if you run the Project it allways get stuck at that block.


Please fix it! I haven't been able to run a propper custom Project in any of the SQX versions so far...
Thanks.
