Galapagos Ran over 186 times, and still running , Only 8 genomes

Hi, I modeled a room with one Window and a daylightshelf that I've been testing with Diva for daylight analysis. I just tried  to use Galapagos , for the Genome I used two sliders, one slider has 2 Diva materials, and the other slider has 4 different heights for a lightshelf.  I started Galapagos last night and when I woke up in the morning I found out that Galapagos ran 186 times and it is still running, I thought it should only run 8 times ( 2 materials x 4 lightshelf heights = 8). Am I missing something?

    I set the results to be exported using Excel Exporter from TT Toolbox plug-in. I export Genomes and the fitness number. I looked at the Excell file so far and I found out that the same genomes produce different fitness numbers in different iterations. For example in the picture below the first column represents the function number , the second column records the numbers on the sliders(Genomes), I highlighted two rows with the same genomes, however the fitness number  is completely different? what is going on?

      Galapagos will continue unless you set a runtime limit or threshold. If you have only 8 possible combinations, it doesn't make sense to use Galapagos. Change the definition so it solves the 8 combinations and then select the best one.

        Another question, what is the square-shaped yellow button in Galapagos, next to the word "Display" and next to the four round buttons. When I hover over it , it says " add mutations to the population" I clicked it and nothing happened, what does it do ? and how do I use it? . Also, I'm not sure what the yellow graph on the top display show?
