Problems with planner

There is a problem with initialising the planner when a saved dive plan
is edited in the planner under version 4.7.5.
Attached a .ssrf test dive plan.
When I open the dive plan as a dive within the dive list, I get the
profile in "Saved dive plan.png". Everything ok. Specifically, the
cylinder pressure is presented correctly.
When I select Log -> Edit in dive planner", I get the profile in "Edit
in planner_1.png". No problem. The cylinder pressure is shown correctly.
Now, the reason for editing a dive plan from the dive list is to do some
more playing around with parameters that affect the deco schedule. In
order to achieve this, the three white points in the ascent part of the
dive plan profile need to be deleted so that recalculation of the ascent
can be performed.
So I start deleting these points, starting with the final point on the
surface at the end of the dive. This results in the profile shown in
"Edit in planner_2.png". Notice that the cylinder pressure graph is
incorrect.
I then select Cancel in the dive planner to abandon the edit to return
to the dive list. This gives, from the dive list, the profile in "After
edit in planner.png" The cylinder pressure is still incorrect. In fact,
the profiles of *all the other* dives in the dive list are also affected
in the same way and I need to restart Subsurface in order to get the
correct profiles again.
Kind regards,
willem
