How do I update work experience section if I recently got promoted?

[Shybutdetermined]

I came to Canada on Feb 12, 2023 and I got promoted in October 1, 2023. In the work experience section do I update this as -
Feb to September - Old designation and October to Present - Current Designation OR,
Feb to Present - Current Designation

Although the TEER has not changed the NOC as provided by company slightly varies. However, both fall under General Category (Not STEM). How should I update my Express Entry Profile in this case?
Thanks in advance

I can't relate the things to STEM? Can you explain further please.

I meant non of my designation - neither older nor current falls under STEM category.

Yes, as in what way could I write? First way or Second Way.

And as a thumb rule, no gaps.
