Yeah, they’re weird! I bet we’ll see parity effects on these puzzles as a
result of what you are observing (say when you unknowingly put one of those
green/yellow pieces in the location of the other).

I’m playing with the "Petal" version, which will be significantly simpler
(doubt I’ll ever be able to solve the others). After looking a little more,
I think one key to solving might be working with what is the white face by
default. That one is different than all the others because it has 5
different color combinations of edge pieces instead of 3. Doing a
commutator with it and one adjacent face will cycle just 3 edges, whereas
commutators with other adjacent faces permutes around a lot more. I just
noticed a commutator of two of the other faces that only share a vertex
alters only some of the 1C pieces, so that should be useful too.
