Hi Sylwia,
That’s interesting.
I noticed you are running the older version of CJT Dev. Tell me, did you migrate to the newer and complimentary version of CJT Dev called CJTe Developer?
The instructions for migration is shown in the newsletter that you may or may not have received.

Let me know if you are still having issues.
Thanks,
Kind Regards,
Damian
