waw....26 relations between the same 2 tables, this must be a record.
I think the maximum number of relation I've see between 2 tables were only4.
Anyway the only problem you will face if you don't rename the relations to something meaningful, is that most robably you won't be able to tell which is which.
I strongly recommend renaming them, even of it's a tedios task, right now, but it will prevent confusion and ambiguity.
But regarding the generatd code, it will compile fine and work fine if you don't rename them.
