The shield of solitude bug (The Elder Scrolls 5: Skyrim)

Disassembled by mistake, the shield of solitude (version special edition). Don't want to replay again as dalekovato already gone. In principle I'm not bagouter and not looking for easy ways, the only thing that does not prevent me to pump the resist magic?. ATO durucu hard against the magical evil high complexity. On the other hand don't want to exploitate bug.
P. S myself I do not fully understand about the bug. Or it increases magic resist or it does not work
