Thanks for letting us know! I have the initial patch option selected in my preferences so I start from scratch every time. Another quick tip for those of you reading!
OR make a combinator with the separate outs to the 14:2 mixer(s). Then your track is like a bus and you can still have full mix control over all your drums via the mixer in the combinator. Do it one time and save the combinator. At least, that’s how I do it
