Lights turn off when moved slightly away from wall

I'm getting very inconsistent results with my light fixtures suddenly turning off when I move the fixture to certain distances away from a surface or wall. In this case I am using a linear family and Linear IES provided by the manufacturer. Very confused as I've never had this happen before. I've attached the enscape render and what you should be seeing from elumtools. Thanks.

The lighting is also frustratingly inconsistent in Enscape and often doesn't match up with the specs and photometrics.
