This dimmer is attached to dimmable exterior led cafe lights. I installed the dimmer switch, got everything set up it was great.  They would dim so much you could barely tell the lights were on which is exactly what I was looking for. About a month in I started noticing they weren't really dim anymore(I usually kept them around 50%). So I tried recalibrating the lights but now 0% is what 75% used to be. I updated the switch already and nothing changed. Any suggestions?
