You may not like my answer , but when prints stain in toners it usually or possibly a fixing problem.

Are you using a double fix routine with hypo clear bath then good wash with great replenishment of water on each print.

I use bleach sepia, gold and selenium, and your second image looks like what I would expect with the highlights picking up that peach colour.

When I am multiple toning as you are , I always wash well between toning steps, and make sure that each print is done.

but frankly this looks like a error in your initial sequence.
