External References

I'm having a problem deleting external references in some parts/assemblies. I haven't had much experience with them but I do know I can lock or break the references but my company doesn't allow that in our standard practices. I've gone through the sketches and deleted all the relations. I've tried fixing the sketches and I've tried to fully define the sketches (under display/delete relations) to no avail. Some become "out of context" references when they were fully defined before and some of the sketches remain fully defined. I was able to fix most of the external references by creating new planes in the part and creating new relations to those planes. I still have some out of context references. Any idea what else I could do?

Thanks!
