Hello Veejay,
Actually, you need to check the box with Resolve Correlations before you run the Reactor. Not after that.
The generator generates strategies all the time and pushes the ones that pass the acceptance criteria in the collection.
The maximum is 100. When this number is reached, it keeps pushing, and in this 100 will come just better and better strategies until the end.
So they are not the same strategies staying in there.
I think what happened in this case, is that the generator found a great strategy with many correlated versions and non of the rest succeeded to show better results. When the generator was over, and you clicked to resolve the correlations, obviously you will be left just with a few.
So try again, but first, check the Resolve Correlations and after that run the reactor.
Also, check the tools if everything is fine.
Cheers,
