Should be not possible to load conflicting DDP profiles.
Only DDP profiles of the same group (not 0) can be loaded
together;
If DDP profile group is 0, it is exclusive, i.e. it cannot
be loaded with any other DDP profile;
If DDP profile groups are different - these profiles cannot
be loaded together;
