Deflection value of sloped beams - STAAD

Hi, I have a series of sloped beams loaded with the same trapezoidal load showing snow drift but the global deflection value I get for each beam appears to be different. I don't think I should I be using local deflection in this case but I'm not sure. The local values are fairly close even though I'd expect them to be exactly the same.

Please I am not referring to the deflection check using DJ1 and DJ2 rather I'm referring to the actual member deflection. This is the deflection I'm referring to

Please assist. Thanks!
