Thanks for replying; I've experienced a background yellowing on prints after selenium/sepia toning myself - I blamed the fixer. I can't comment on the Moersch fixer as I've never used it.

I'm not sure whether the thiosulfate in selenium toner is strong enough to fix prints, but it can erode fine details if residual toner isn't removed before bleaching (been there... I'm not sure how it might affect direct toning though).
Sepia toning before selenium might help you find out where your problem is occurring, and at least eliminate or confirm the selenium toner as the source of the problem.
