Magnet Field - mmGPS Setup vs. Pocket3d - mmGPS Setup

I am having some continuity issues when trying to setup our mmGPS system with my Magnet Field software. To give you some background information, we have set up a single LZ-T5 laser on a known control point, calibrated it, and tested it using Pocket3d, checking in perfectly on several control points. However, when I attempt to set this up in Magnet Field I consistently shoot .08 low on control points. I assured all my control information was constant, the slant/mark measurement on the laser is the same, and the control point it is set up on is correctly entered in magnet. I can tell i'm overlooking a simple setting somewhere that would affect the height of either the laser or the instrument, but I can't seem to pinpoint where that setting is. 

I have ensured the height of the laser, height of the antenna with mmGPS receiver, and the control point the laser is currently on are all correct and match what I used in Pocket3d. To further this, when I point the receiver away from the laser while setup on a control point, my elevation is perfect, which, as previously mentioned, is what is leading me to believe there is a simple setting that affects the height. 

Thanks for the help
