Before I file the issue into github, can anyone check for me an order of logging severity levels in HA 2021.10 (I’m using v2021.9.7).
Here is how it looks in Service tab:
Even official docs mentions proper order
Possible log severity levels, listed in order from most severe to least severe, are:
critical
fatal
error
warning
warn
info
debug
notset
It is because it is listed alphabetically in UI. Probably because it is formatted somewhere in the code or with a linter. Though i agree with you that it should be listed in the same order. 
It’s sorted alphabetically using what language? c-f->e? e-w->i ??
Just saw it 
Well if you ignore debug it is 
And I was/am referring to the dropdown
yeah you are right, my fault.
seems that currently selected mode is always on the top, then the rest is alphabetically ordered.
