There is no option on the popup menu to change the condition of #19 Commissar Dottski to “KIA”
I think it might be better to look for the module mantainer and see if they’re willing to do an update than postning this in the forums, especially in multiple posts.
also you should be more specific. There are at least two different Up Front modules hosted in vassal website. One of them doesn’t suffer any of the problems you mention or (hopefully) any of the others you have not mentioned yet. OTOH it just includes basic UpFront: no banzai! or other expansions.
