Linking Slicer between tables

I have 5 worksheet, each with a different data set, but all have a common data type (column), I have inserted a table in each worksheet, on a new sheet I have inserted a Pivot Table, Then used the data model to generate 5 new Pivot Tables, each looking at one of the tables in each of the WorkSheets. I have created a relations ship between the first table and each of the 4 other tables based on the one common types (column), I have inserted a slicer for the first Pivot Table and then with the Report Connections menu have linked the slicer to the other 4 pivot tables... I have learnt this from You Tube... and it was fairly straight forward.. But it doesn't seem to work.. any suggestions??

The spreadsheet is too big to load up... I'll try and amke a new one with a smaller dataset and see if I can replicate the problem

A new slimmed down version with dumby data.. but still a problem
