Magenta

I have been trying to print b&w photos from lightroom classic and keep getting a magenta cast. The same effect you see if you don't tell the printer to print b&w or gray scale. I'm converting to b&w in lightroom making some adjustments and printing on an Epson P600 allowing the printer to handle the color management. I use the printer's advanced B&W settings. The same problem occurs on all three Epson printers I have access to.

If I export the file as a tiff and print it from Preview, Capture one or Luminar it prints out b&w no magenta. If I import the file to lightroom convert to b&w make no adjustments it prints b&w.

I really don't want to burn through a ream of paper to trying and figure out which adjustment is causing the problem. I hope some one has an idea.
