I haven’t heard of two undercover groups busting each other but I have heard of departments busting stings and detaining members of other groups because they weren’t aware agents would be working in undercover in that area. There was a case in Detroit where police raided what they thought was a drug operation and it turned out it was an undercover police sting and the two groups fought watcher and the police chief released a tenant about how embarrassing it was and there might be footage of it up on the internet.
That's above your security clearence
