Etsy Rejects Additional Customer Review Filters After This A/B Test

Here we can see additional customer filters being added for two more variables: "With photos" and "Filter by rating". Given that in past experiments we usually observed authentic customer photos perform better, I'm doubting that this had a negative effect. Could the rating filter have allowed customers to shift focus on only the negative reviews in a less balanced state? Hard to say. 

As part of this variation, all three filters also gained additional visibiltiy from a ghost button style (with a thin border). Given that buttons usually gain more attention, could this have come at a cost to other critical elements or actions?
