conditional formatting lost when USERELATIONSHIP ist used

So this is my visual Table: (the last column is there due to the USERELATIONSHIP otherwise, the data would now show when I filter with Sales Manager from the second table. 

Table 1: 

Table 2: 

The issue I'm facing is with the "processing quality" column, which has conditional formatting. Specifically, cells that indicate "on-time processing" have a green checkmark, while cells that indicate "SLA exceeded" have a red cross and a red background.

However, when I filter by Sales Manager "Christian," I get all the data based on my helper column (the last column in the table). The problem is that the formatting disappears for all ZIP codes where the Creator ZIP does not belong to Christian. Since he is the Processor, the formatting should still be applied.
Additionally, I used the USERELATIONSHIP function in the table to manage the relationship between the Creator ZIP and Processor ZIP.



Here is also a screenshot of the issue. The conditional formatting should be applied to all of the data

ps.: In the screenshot the second ZIP Code should be the Processor ZIP
