85070E High Temp probe calibration

I am using 85070E High Temp probe kit with E5071C VNA, with ECal. I found that with the 3-standard calibration, when I choose air, short + distilled water as calibration standards, then measure other samples like methonal etc..., the sample dielectric values are different then if I choose air, shor + fused quartz as calibration standards. It seems my measured sample dielectric constant is very sensitive to the choice of the third standard (water or other minerals that I know perfectly dielectric constant). Has anybody found this problem before? This does not sound very logic to me...
