How to Maintain the freeze pain of top row in plece whan you sort?

[yenom2]

I have a spreadsheet and I froze the top row, before when I sorted the top row did not move and stayed as the title for the columns , now it is moving with the scroll.
How do I keep the top row not to sort and stay as a title for the column?
Thanks

When you sort, make sure that the "check if range has heading" is checked
Or dont include the heading in the sort range
