What is the reason for while exporting why note layout are changing

What I’m trying to do

I just wrote everthing what i want, but after export as PDF the note layout is changed.
I wrote one line and after i added a point after that i wrote a sentense that’s not points in the UI is ok, after export as pdf the second line after which after the point, the sentence is aligned to the point.

This is i wrote.

This is after export.

Things I have tried

I eported multiple time but its happaning again.

Click this book icon here:

That will switch you to “Reading view” which will be the closest to and probably matches the PDF export.
