Aren't you looking at the Last population databank?
When your databank is full SQ wil replace the weakest strategies, but it doesn't replace the oldest strategy.

Attached my settings file. Here, EURUSDe refers to EURUSD Dukascopy data cloned to America/New_York timezone. (Suffix 'e' at the end of symbol means "Eastern Time Zone")
The expected behavior in this case is: Generate 20 strategies (2 islands; 10 per island) and then start evolving with initial population. However, it keeps generating random strategies upto 500, and after that, replacing the weakest strategy. The "initial population" tab is always empty.

It works as you say, but you don't see it:
1. Initial population databank is there for you to load strategies if you want to use some existing strategies as initial generation for evolution. If there are no strategies, or less than required then SQ will generate the initial population randomly.
But strategies generated by SQ are not stored into this databank. Initial databank is for input, not for output of strategies
2. you don't see the genetic evolution in results databank. With your setting the genetic evolution in SQ is very fast, you don't see how it works. All strategies from genetic evolution are sent to Result databank.
You have Result databank configured to contain 500 strategies (Settings -> ranking), and when the databank is full and new strategy arrives then it replaces the weakest strategy in databank.
3. if you want to see the generations you can turn on "Show last generation in databank" option in Settings -> Genetic options -> Evolution management.
But in your case it runs so fast that you'll not see anything meaningfull.
I woudl recommend you to increase the population, 10 is very little. You can have 100 strategies per island.
