Switching to lvl 100 skins is the "fix" for the time being. Though they have the wrong color reaction - the one intended for the corresponding lvl 110 skin. I think some of them look pretty cool that way.
This is related to the weapon skin bug, which you have doubtless noticed by now.. In your inventory, the skin name you will see is the name for whichever skin was created NEXT for that weapon. If you have the last skin created for a weapon equipped, it will instead show the name of the next weapon in whatever order the game stores them in. A couple of weapons have newer skins coming that haven't been released yet, and if you are using the most recent skin for one of those, your inventory will display the temporary code name for that yet-unreleased skin. So, along with the name for the skin, in the case of reactive skins, the game is also applying the VFX for the next-created skin for that weapon. Lvl 100 skin gets the 110 skin VFX, and lvl 110 skin gets none.
I hope I explained this adequately, it's a bit complicated and I don't want to write an essay. Credit to a couple of smarties on the reddit sub who figured all of this out when the bug began.
