Character autocomplete not in all-caps

In screenplay mode on iOS (haven’t tried macOS version yet) when you start typing a character’s name and autocomplete, it properly writes the name of the character in all-caps.

On Windows, however, this is not the case. It does autocomplete, but in normal case.

Any thoughts?
