[cmano]

Hello guys.

I have create 2 table boxes and as key Field Notification (red circle)

When i haven't select notifications the 2 table boxes bring all the values on the fields (see above).

When i have select some notifications from the 2 tables only one(the above) bring all the fields filled. The 2nd brings only Material and Notification field filled (see below).

Why this happens? Any ideas and how i can solve this?

Best regards.
