Changing Names of Slicers is Prompting an Error

Hello again. I'm getting an error (end/debug) message thrown when I change names of the slicers, both in the Data sheet and on the Slicer itself, and then try to update the PT or Reset the PT.
The error is showing on Sheet2 (BuildMyBOM). Select any of the Items to the left and then select Reset. The line that is being highlighted is:
If Not ActiveWorkbook.SlicerCaches(SlicerName).SlicerItems.Item(1).Value = "N/A" Then
I’ve updated the Data sheet, I’ve updated the slicers, I’ve updated the code to the best of my abilities. I’m not sure where I’m going wrong. Would greatly appreciate if someone could take a look at it for me and provide some insight. Tks.

Maybe explain what you are trying to achieve with the macro?

I was only trying to change the names of the slicers. Rating became Class/Rating. Class became Approvals. Requirements became Special Req. I changed it on the Data sheet. Then I changed the slicer name. Then I changed the macro. Basically update one, update the rest. After changing the names, the Macro no longer works...or rather it works, but with an End/Debug message. When you view the code, the below line is highlighted.
If Not ActiveWorkbook.SlicerCaches(SlicerName).SlicerItems.Item(1).Value = "N/A" Then
So, I'm trying to figure out what I need to do to make it start working again. If I change the slicer names back, it works fine, but I kinda need to make these changes. So, that's where I'm at with it. I also tried refreshing the PT and inserting new Slicers. Still not working. Tks.
