What type of operating system are you running?

[VolkerK62]

due to IEC standard, 6A is the minimum.

[jomuench]

due to IEC standard, 6A is the minimum.

thanks @VolkerK62 - I wasn't aware of that, just tried what the UI offers. Going to mark this issue as n.a. or something.

[jomuench]

not an issue but rather kind of confusion as the UI is offering settings that are not possible due to technical restrictions.
