what is going is is: Selecting VPM-B as deco model also selects it for the logbook part for the display of dives. So, this setting should better be in the preferences. On the other hand, you want to be able to access it from within the planner to have control over the differences that choosing the model makes for your plan.

Besides that, I think, everything is fine. As this is a different model to Buehlmann, the ceiling is different, I see no problem there. And it is a strange model, so the fact that there is a (very very shallow) ceiling for a dive with EAN32 to 15m does not really surprise me.

So, I guess, the only thing that needs to be fixed is to make the choice of deco model available in the preferences.

PS: In the 4.5 branch, the model is not correctly shown in the profile.
