Excel spreadsheet won't sort all columns together

Hello.  We have a spreadsheet from one of our users, where he added 3 columns (N,O,P) onto the existing sheet, and while they look like the rest of the columns, there's something about them that will not allow N,O,P to be sorted along with the rest of the worksheet.  A thru M can be sorted, and N-P - but not ALL together...the SORT function becomes greyed out if you try.  I want to try and resolve this without attaching the file, if possible (sensitive info).  if absolutely necessary, I can create an abbreviated version of it perhaps.  

thank you in advance

Make up a simple version that you can post that demonstrates the problem.  That will give us something to work with.  Otherwise, we're just guessing.
Is it possible that your data is formatted as a table and these additional columns are just a range?

Edit: If you try to sort Range and Table together Sort will be grayed out.

Ok - I figured.  here you go.  

Yeah - I'm not sure if its a mix of table and range, actually.

Ok - it says I need to remove AutoFilters before I can do that.  I'll see if I can find where that's set...
