Filtering by BOTH Criteria not Either

Hello, I have some zip codes with sales data. I have it on some tables and a map. If I filter by clicking on Albert and Mary in Table 1, my map and Table 2 gives me the zip code that has sales for EITHER  Albert OR Mary. I want the zip codes that have sales for BOTH Albert AND Mary. Any suggestions on how can I do this? If I have to use a method different from these tables it would work too. Thanks in advance.

(I am familiar with SQL but I am fairly new in PowerBI.)

Table 1

Table 2
