cannot customize commands for choice section

[Will]

I have a choice group and I'm trying to customize the commands for the
shortcut menu. After opening the section properties and clicking
"Customize Commands", the only action I can customize is "ReplaceWith".
The other commands (insert, insert before, insert after, etc) show up
in the shortcut menu, but I cannot change the text. Does anyone know
the reason for this?

I still don't know what caused this problem, but I was able to find the
correct section of the .xsf file to customize the values .
