Removing blanks where blanks show blank but are code to show blank.

Hi Guys
I have the following code which was kindly given to me by a colleague at ExcelForum. It was designed to remove one row if that row was empty which it does. I have tried to use it in another location where there are several hundred blank rows which it was not designed for and takes a very long time removing some. Eventually having moved some it gives up.
Firstly I can’t work out why it is removing some as they appear identical to the ones not removed
Secondly it is very slow.
So is there any code that would remove these blanks.
Here is the code I have

'This will remove the blank row only if there is one
'Sub checkTwoCols()
'Option Explicit

    Dim cel As Range, rng As Range
     Set rng = Range("A2", Range("A65536").End(xlUp))
      For Each cel In rng
        If cel.Value = "" Then
            If cel.Offset(, 2).Value = "" Then
               cel.EntireRow.Delete
            End If
       End If
    Next cel
End Sub

The problem is that I have now run a macro to pull from another sheet the data I need. The macro shows “ “ in the cells I do not need but behind that there is the code. I do not know how Excel recognises this. If anyone has a suggestion I would be thrilled.
I am uploading the workbook which puts my comments into context. The sheet I am working in is Petty cash and the data is being pulled from BDC2. The macro (4) has just been run. There are entries in the petty cash sheet. Some of the columns are hidden because there are not needed.

Thanks in advance
