AC Ohmic Losses get reset to zero

[wjwlitespeed]

I have a project with several arrays. For the AC Ohmic Losses, I selected "This Sub System" and set different loss % for each array.

When I return to the Ohmic Losses tab later, the AC Loss is reset to 0% for all but Array #1. The values I entered are gone.

I am running V6.25
