What are your folders in this case? Projects?
You can look at your grouping settings for the Test Explorer.
You find Grouping at (1), ensure that in the dialog, the grouping is set as shown (2).

Note also that NUnit doesn't select what tests to run. It accepts what comes from the test explorer. You can check that using a .runsettings file, and enable the Dumps there, see https://docs.nunit.org/articles/vs-test-adapter/Tips-And-Tricks.html and https://docs.nunit.org/articles/vs-test-adapter/Tips-And-Tricks.html#dumpxmltestdiscovery-and-dumpxmltestresults

If a test has two categories, in this case both Integration and Unit, it may look like this.

Check the filter being sent to the adapter, in the dump file. Then look at some of the tests that have run and check what their categories are.

If it still looks wrong, then upload a small repro project. But again, the adapter just runs what is being sent down to it from the Test Explorer.
