Given that the dive preferences have been set to a Max PO2 of 1.6 bar, the expected MOD for O2 is 6m and for EAN50 it should be 22m. But it gives the MOD as 4m and 18m respectively. That is erroneous. There appears to be no way to convince the planner otherwise.

I use the planner rather frequently and I did some planning before upgrading to V5.0.6 and those plans were not problematic. I am not absolutely sure which version I had before 5.0.6, but I am reasonably sure it was 5.0.5. I can only assume that the planner accesses the preferences file and gets some information there that is not used correctly. I am at a loss to explain this behaviour, even in older versions. Consequently I have this nagging fear that it is finger trouble on my side and I am making a fool of myself.

currently, I am somewhat busy. I will look at it, as soon as I have some time. I am sure, there is a simple explanation, this used to work.
