"<date> contains invalid character(s)” in schematics page settings

I remember a similar report a while back:

Invalid characters when setting date on drawing sheet

Hi all, I am trying to change the page size of my schematic, however, an error pops up showing that my date contains invalid characters. Please see the screenshot for details. Does anyone have the same issue and how do you fix it? Thank you! TNG [Screenshot at 2023-03-02 22-21-09]

There it got fixed by the user changing language to English and then setting the date. I don’t know whether it was a bug and if so it got fixed. Also I note you are still on v6.
