D-LOOPS

that should never happen it must not be for bows d loop should last for a long long time.i would go to a new shop or buy your own and tie yourself takes 1 minute and is easy

Very unlikely it's the release. 
 
It's more likely the material being used.   Gotta be careful what kind to use.  Archery shops use the cheaper stuff, considering they sometimes do the loops for free...  usually the shoe lace design junk.
 
I'll try to find you a link to "the stuff."
