Pivot Table & Slicers

I'm fairly new to pivot tables & slicers but I like what I see thus far.

The slicer I'm concerned with is the "GAP" slicer. If you look at the #'s you'll see some #'s listed twice. For example, -2, 1, 2, -3 are all listed twice. I don't know why this is happening.

The purpose of this # in the GAP slicer is to only show accounts that have that GAP listed from the "Table Data Base" which is where my table is. For example, when I click -2 I see many accounts that have a gap of -2 listed. Then I click the other -2 & see a total different list. But both lists are correct in that the account has a -2 gap. Just no idea why it's showing up twice.

There might be a better way of doing this. Ultimately the ONLY important data in the "table data base" that this # means anything is the account name. But the only logical way I could find to import it in was by V Look up from the "tap count" data base. But the problem with that is it enters the # every time it matches with the customer #.

EDIT: I can only provide a screen shot. My file is too big. 1.3 MB. Site has a 1 MB limit. I can always remove some of the data but before I do that see if a screen shot can help with the answer.
