SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***


STEPS TO REPRODUCE
1. Regional Settings
2. See that the "Formats" Settings are missing entirely
3. Go instead to Region & Language
4. "Modify" "Time", see that no locale actually has the date Format, that is required with no setting to set the correct format
5. apply any other date format just for the fun of it
6. restart system
7. observe that no change to the date format has occured anywhere

OBSERVED RESULT
multiple settings went missing. Existing settings don't work

EXPECTED RESULT
settings to stay where there should be and work as expected

SOFTWARE/OS VERSIONS

ADDITIONAL INFORMATION

Can you paste the contents of `~/.config/plasma-localerc`?
Comment 2 pingger_kdesucks 2024-01-07 17:50:07 UTC 
`~/.config/plasma-localerc`:
```ini
[Formats]
LANG=C
LC_ADDRESS=C
LC_MEASUREMENT=C
LC_MONETARY=en_DE.UTF-8
LC_NAME=C
LC_NUMERIC=en_DE.UTF-8
LC_PAPER=C
LC_TELEPHONE=en_DE.UTF-8

[Translations]
LANGUAGE=C:en_US

```

Just to be clear, the DateFormat I want is ISO 8601, aka YYYY-MM-DD'T'HH:mm:ss+zzzz (where the timezone is optional if UTC+0, but the 'T' is not, and this being the short form. the long form would include milliseconds)

I know, that this setting was possible in the past, but has now disappeared from the UI, in addition to the UI not changing anything (except apparently this non-standard file, that has no association with the actual system settings in `/etc/locale.conf` or in `~/.profile` (or at the very least in `~/.config/environment.d/`) where it would actually belong!)
`/etc/locale.conf`:
```bash
LANG=C.UTF-8
LC_ADDRESS=de_DE.UTF-8
LC_IDENTIFICATION=de_DE.UTF-8
LC_MEASUREMENT=de_DE.UTF-8
LC_MONETARY=de_DE.UTF-8
LC_NAME=de_DE.UTF-8
LC_NUMERIC=de_DE.UTF-8
LC_PAPER=de_DE.UTF-8
LC_TELEPHONE=de_DE.UTF-8
LC_TIME=de_DE.UTF-8
```
