When will cursor stop "behaving"?? Is that too much to ask?

Another BASIC editing funtion.
I place cursor on one place and hit enter  but new row is created on totaly another place.
Just after muliple times it will finaly create a new raw where it needs.

REPORTED MULTIPLE TIMES in various posts.
Support - I am not interested into providing you details again, link to notes again, videos again. I did that already multiple times.

Writing just to say that NB is nightmare to work with.
