Getting error after clicking on "Start Deep-Copy" in FPM for MDG custom object

Dear MDG experts,

We want to create custom master data object in SAP MDG. we are using ECC 6.0 ehp5 .

In UI modelling step  we started "Edit UI configuration" and clicked on "Create"

After changing the target configuration id for "Application Configuration" we clicked on "Start deep Copy".

We are getting error

Deep-Copy: Not all configurations have been copied

Please help us to resolve this issue.

Thanks and Regards
