NullValueRetriever works in CreateSet but not in CompareToSet

[Navis62]

Hello
I am using the latest Reqnroll (3.0.2), NUnit 4.4.0 and latest JetBrains Rider
I created a BeforeTestRun Hook in my test project to setup the NullValueRetriever using "[NULL]".
When I use table.CreateSet to setup the actual values, it works fine I have null values, but when I try to compare it with the expected using table.CompareToSet, the expected has still the "[NULL]" strings.
Is it a bug or should I do something else ?
Regards

Sounds like a bug to me. Could you please try to create a PR (with tests) or just some unit tests to show the issue?
