Shure ULX Frequencies changing by themselves

Hey CB,

We have 4 shure ulx handheld microphones (j1 band) we use in our space and we have this recurring issue where the mics will magically reset their groups and channels (sometimes in the middle of a performance) back to group 1 channel 1. They'll also randomly switch between a group x channel x setting and a group xy channel X setting (like from group e1 channel 9 to group 1 channel 1) with seemingly no rhyme or reason.

Anyone have any experience with an issue like this, or know of any possible causes? There doesn't seem to be a pattern to it, with it just occurring randomly.
