Sage Intelligence - Sale Mater Report

Good day

Kindly advise,  when the Sage Intelligence Sales Master is loaded of sage 200, it is showing  the names of Customers that are on the database system. How is this happening or possible?

If you open the excel file and refresh the data, and you try to filter the customer code name in the first column one sees customers that are not of the company data

The excel is however pulling correctly but (Filter option) is showing customer that are not in the company .  

What might be the problem?

Kind regards
