I have no expertise here but I worry that these trials are studying the decision-making processes around how people decide to use the information from these tests, rather than the tests themselves.

How people use information varies, so the data might not have external validity - it’s culture specific, and cultures differ. Cultures can also change through accumulated experience.

So do the people studying these things try again with different and possibly better decision-making, or do they conclude that the test itself is no good?

That is a very important point. This is why multiple studies are needed that across time, location, culture, etc. The more data a doctor has the better decisions they can make for their specific patients.
