I'm looking into it, but would like more information if you can provide it. What SIGIL color? What GATE color?
Edit: I found a RED SIGIL had unusual scripts which allowed it to be picked up slightly "differently" than the other SIGILS, which could perhaps be your issue. I can't understand how in any circumstances you might pick up more than 1 SIGIL at a time though, so are you sure it was two SIGILS and not a SIGIL and a LORDSTOP? A LORDSTOP could be used up right as you open a gate if a LAYER LORD was lurking on the other side, emptying your hands entirely as it were.
