simple column delete, overlapping sections error?

Sheets("Raw Cost Data").Select
'   This is the list of columns that are to be removed.  If source file changes, update this list.
    '
    Range("A:A,D:D,E:E,G:G,I:I").Select
    '
       Range("I1").Activate
    Selection.Delete Shift:=xlToLeft

Simple... It deletes the columns listed in the range...

I even used the record macro to double check and it spits out the same error...

There are merged cells, but none are the left most cell, none with any values, doing it manually causes no errors or warnings at all.

I just went at it from a different direction, copying the columns I want instead of deleting those I dont. works... but Im curious if anyone knows what the issue was.
