Duplication of Categorization schema

Hello Experts

I defined Categorization schema

category 1 has in number 1

category 2 has in number 2 drop downs

category 3 has in number 10 drop downs

category 4 has in number 20 drop downs

i created for category 3 has in number 10 drop downs and copied to 2 drop downs in category 2

i created for category 4 has in number 20 drop downs and copied to 10 drop downs in category 3

but while testing i can see categories .if i select each by category wise ,those categories are tripping (Jumping to other category)

Below warning message iam getting

Category ID "CA_131" is not unique ( 2 occurrences)

Since i copied Category nodes to Rest , seems it is not unique, so i changed category ID manually for few

then above warning message disappered for that category node

but should i change Category to all Since i copied to other Category nodes. it is difficult for me and killing time

kindly suggest any other alternate solution other than manual change of Category ID's

Regards
