Example: 2 folders do not belong to the same tree structure in a BIM360 project but have the same attribute name (example: XYZ)
If one of the folders is moved to the tree of another - Custom attribute will be duplicated. (2 x XYZ) This is due to ID`s of the CA`s which are unique for the corresponding folder.
Would be good to ask a user, if he wants to make a duplicate of the attribute or use the destination attribute as main.
Also, should apply to values in those attributes.
