Version 9 doesn't adjust for minimum input voltage

In version 8, as I increase the VACMIN specification in PIXls Designer, the specified inductance goes down.
For example, in the three ver 8 files attached, I changed only VACMIN, and got different LP specifications, as follows:
VACMIN = 85V LP = 969 uH
VACMIN = 93V LP = 863 uH
VACMIN = 100V LP = 834 uH
If I then try the same thing in version 9, I find that as I raise VACMIN above 93V, the specified LP does not change.
VACMIN = 85V LP = 872 uH
VACMIN = 93V LP = 801 uH
VACMIN = 100V LP = 801 uH (same as 93V value)
(Note that with VACMIN=85V, the LP value in version 9 is 10% lower than that in version 8. With VACMIN=100V, the LP in version 9, is only 4% lower than the ver 8 value.)
