... One of the drawbacks of diffraction grating
based instruments I guess.
And maybe also of 45 degrees illumination / 0 degree
measurement devices compared to 45 degree measurement and
0 degree illumination.
In principle they should be equivalent but in practice,
the straight measuring path may be more sensitive to
polarization. A 45 degrees circular measuring field would
"mix" the incoming light and de-polarize it, but a low
cost design would likely be more expensive to manufacture.

Please include your instrument model in your answer.
I think I mentioned on this list a while ago that
the Spectrolino also suffers from this, to an even worse
degree. One of the drawbacks of diffraction grating
based
instruments I guess.
You'd just better hope there aren't wavelength dependent
polarization degree or angle effects too.
