Pasting Pivot Chart Format or using slicers Changes Pivot Table data Reference

So I have a very wonky problem and have been looking for a fix for this issue and havent located it yet. I registered specifically to ask this question.

I work for a large retailer and have built a large spreadsheet to work as a functional dashboard using data that is prepared in a number of formats using pivot charts and slicers. The problem is that some of these graphs appear unstable. Basically some of them when they update format via slicer or pasting a chart format will break their reference to the pivot table that drives the pivot chart and instead remaps the chart to pivot table 1. I usually create my pivot tables based off of just copying and pasting the pivot table next to it and wondered if the chain of tables may affect it and created a pivot table from the root data table and it had no impact on the problem.

Does anyone know why pasting a chart format or using a slicer would cause a pivot chart to change the pivot table data reference? The problem is I can build each chart manually instead of pasting the format but those charts where pasting the format is an issue also have problems with slicers so when users use the file the charts corrupt and start showing information from another table. IE my pivot chart will reference pivot table 12, but when i slice or paste a format the chart then references pivot table 1. The chart i copied the format from wasn't even referencing pivot table 1.

Any ideas?
