Freeze row function does not work

my finger hurts from choosing top two rows and then trying to freeze them so I can see them when i go past the first page. Doesn’t work. What am I doing wrong?

From https://help.libreoffice.org/Calc/Freezing_Rows_or_Columns_as_Headers:

Select the row below… the row… that you want to be in the frozen region.

So select row 3 in order to freeze rows 1 and 2.

Seems a little strange to me as well – my first attempt was to select the first two rows but that does not work as expected.

This question has been answered before, so next time be sure to search before asking.
