Don't worry... Be Happy!
Many new films have distinctly colored anti-halation layers that come off
during developing. A pre-soak is only recommended if you're using
replenishable developers... not "one-shot" developers, like Rodinal... and
mostly just to keep the person doing the developing from "Freaking Out"
over the color of the developer in his container, in his darkroom...
there's no effect on the developer, itself, and most often... the color
dissipates, anyway.
