LB130 no color change and vanishing slider (0.50.1)

Hey folks, now sure where this belongs. I upgraded to 0.50.1 and added in my TPlink LB130 bulb. I can control it’s brightness, change the white hue, and turn it on/off. However I cannot control the color:

Config:

light:
  - platform: hue
    host: 192.168.9.204
    scan_interval: 30
  - platform: tplink
    host: 192.168.9.199
    name: Den

You should report this on github, clearly it’s a bug.
