While the gremlin damage change was documented and now matches the fact sheet better that comes with the help menu...
The Thwackers (didn't notice for other gremlins) in tier 3 are still showing their little attack indicator (the W at their feet as they wind up) as red for normal damage, not green for elemental.
Noticed today that scuttlebots in tier 3 have the same issue.
They're doing elemental damage, and green attacks (when they don't do status) but their attack charge is showing up as red in front of them.
Some of them even seem to be doing pure elemental damage, but still displaying red while they charge.
