Sorting problems!

Sorting problems!

Very simple sheet, no formulas.

First row labels (DATE, NAME, ETC) which I've "set as text" so it won't sort along with the data.

I only sort by column A (DATE), I select the column, right click sort descending, I'm SURE to answer OKAY to "expand selection?", and yet.... my dates have gotten hopelessly fucked up. Sorted without the rest of the data in rows.

Or, sometimes the column just WON'T sort-- data seems frozen.

Only been using this for about a week, I'm afraid to keep using it for fear of all the wasted work down the line.
