Why does IntelliJ show related problems when methods are not related?

[Punpun1643]

While trying to implement some methods, I realise IntelliJ sometimes show "related problems" for the methods. An example would be for this hasGroup method.

However, upon inspection, I realise the related problems are in tests that use other methods that are not related. An example is the tests that use hasPerson method.

I'm wondering why this is so. Although I am able to pass all the current test cases so far.

@Punpun1643 See if File -> Invalidate Caches help get rid of the problems indicated by Intellij.
