It is global bug however.Tested Shelter and Jareth, Leonine Titan and both suffer from the same bug.Also we have a similar report open about auras that don't fall off from animated lands that stop being creatures:

It works properly on much fewer sources of color protection, mostly creatures that have it continuously, than it's broken on. (Irritatingly, it works on the alpha wards like White Ward... without the "This effect doesn't remove White Ward" part.) The situation is much more dire for non-color protection, and for auras' enchant clauses that are no longer met in general.

The way auras are programmed in Manalink makes the problem extremely difficult to fix, short of rewriting all of them individually with this specific problem in mind. It was actually one of the motivating cases that got me to start over in Shandalar instead of trying to port Manalink's duel.

Like Korath said, it's a problem difficult to fix...
In the meantime, I added a block of code to both 'generic_aura_impl' and 'targeted_aura_impl' that takes care of color protection from the colors of enchanting aura in e7a4a69
This will break the "This effect doesn't remove..." clause in cards like White Ward, but doesn't seem a great loss from my point of view.
As for the other types of protection... Stay tuned.

This has been fixed by work on auras by drool66.
