I have two HS220s installed in my house. One that is causing issues and one that is not. For the one that is causing issues it is connected to 4 Slim LED canless lights in my kitchen. The lights turn off and on and dim as they are supposed to however when they are on the will occasionally flash off and then back on. The link for the lights I installed is  https://www.homedepot.com/p/Commercial-Electric-Ultra-Slim-6-in-Color-Selectable-New-Construction-and-Remodel-Canless-Recessed-Integrated-LED-Kit-91477/310114092 . I have rechecked the wiring and ensured that all of the wires are functioning and connected as they are supposed to. 

The other switch works perfectly and is connected to a single LED light. The link for that light is https://www.homedepot.com/p/Halo-SLDSL6-Series-6-in-2700K-5000K-Selectable-CCT-Surface-Integrated-LED-Downlight-Recessed-Light-with-White-Round-Trim-SLDSL6069S1EMWR/314896280 . 

Any help would be appreciated all of the lights are at the brightest 5k setting.
