Installed Shelly Dimmer, strange behaviour with switch - Hardware

Sooooo did the firmware update as soon as it came online. And I turn it on and off in the app and in Hass, via a custom component. But when I use the light switch nothing happens unless it’s already on and then if I quickly flick the light switch on and off it turns the light off. It’s wired just like the included picture, very strange, should have tested on the out the box firmware first tho. 20191127-095929/v1.5.6@0d769d69 Anyone for any ideas?
