Auto Format Breaks Writing Simple Dates

### ⚠️ This issue respects the following points: ⚠️

In case the issue is resolved there, you don't need to create a bug report. The change will be part of the next Markor update.)

### Description

I want to write down some dates in separate lines - german format like
"5. April 2024"
As soon as i hit enter Auto-Format changes it to
"1. April 2024"
Because its regarded to be a list.

This changes crucial Information and the first times it happened to me i sometimes didnt even notice because i went on with the Text, not expecting any changes at that point.

I think auto-numbering Should only start with number one followed by a dot.

Workaround is to turn of autofomat for the individual file, as stated in #2436

But the default setting is the Problem here.

There is a related report ( #2436 ) that refers to this behaviour happening on pasted information with manually sorted lists being changed.

Thanks for markor!

I did not try latest development Version but thats out of reach for me and it exists since years

Reproduce the issue in Markor with Auto-Format enabled by entering “5. Anything” and pressing Enter. Trace the editor’s auto-numbering or list-formatting behavior, then verify that dates such as “5. April 2024” remain unchanged while a list beginning with “1.” still formats correctly.
