Name Manager changing my range after I run a macro

Hello all,

Got a weird one here. I have a workbook that has a saved range. I created it with the Name Manager. See below:

When it looks like that the VBA works great and creates my pivots. But after I run my first macro to mess format my source data the range ends up looking like below:

It is for some reason changing the "A" to "Y".

Any thoughts on how I can get it to stay with the original data?

Thanks
