My thinking exactly. About 1/3 of my lights are dimmable only (old Cree bulbs that I just can't throw away because they won't die and I'm cheap) 1/3 are CT only and the rest are RGBW. The CT have some funky stuff going on with Color name too...but again, that doesn't really affect functionality, just my OCD. 
Turns out....it was the "alert": "none". Took that out...bingo, no problem. I knew it would be something silly like that.
