I would hope not a bug, wouldn't be too sure how to fix it
Did you put in 2 for both the spiral and big or just one in each?

Hmm, yea not sure, just redownloaded it and tried all 4 ways to do it
PO C GlBk; OP C GlBk; PO C BkGl; and OP C BkGl all worked right
If you're saying 2 for each, make sure just putting one in the burner one, otherwise the only hting I can think of showing is direct button click steps to make sure it's done right but even if that didn't work would have no idea
