Label capitalization query

i did play around a while ago with capitalization on an Label.
the result was not great, not what i would expect.

i would like to have just two options:

  • no capitalization
  • mixed cap, so first char

but i wanted to have that just during user input
the current result now is: even lower case input is capitalized on load when i use the mixed …

does anybody know the propper setting for that ?
or do i need to set that manually only in edit mode, that would feel strange imho
