How do I filter by 'exact match' in iPhone App?

[Catherine]

When I filter labels by "exact match" on desktop web with multiple labels, I get cards which contain all labels selected. Plus still shows the card if it has extra labels. This is the result I want.

When I try the same on mobile, it either shows me any card with any label selected. Then If I use "and" it will show me cards with all labels selected, but does not show the card if it has an additional label.

How do I get the mobile app to produce the same result as desktop web?

The board with filter:

Then I checked on Android and after manually filtering the colors I got the same result:

Could you share the differences in my test? I'm on the lookout for your reply!
