Help with URL Filters (Special Characters?)

Hello,

I'm having trouble implementing a url filter and I'm wondering if anyone can help me figure out what I've done wrong.

Here's the url/query parameters:

[url]?filter=SLA_x0020_Query/Bldg._x0020_Region in ('NorAm West', 'NorAm East')

Table: "SLA Query"

Column: "Bldg. Region"

Values: "NorAm West" and "NorAm East"

I replaced the spaces per https://docs.microsoft.com/en-us/power-bi/collaborate-share/service-url-filters but that doesn't seem to work as expected. I've tried replacing all the spaces in the url, none of them, some of them. I can't seem to get this to filter appropriately.

What have I done wrong?
