I'm using search API and facet API as part of my Commerce Kickstart install. I have an issue with the price slider in the facet display. The lower price boundary for my items is $9.57, however this option is being rounded up to $10. Therefore if someone makes any price filter search at all, it will always exclude items below $10, as it is impossible to move the slider below $10.

Could someone advise me on how I would fix this to show the correct lower boundary, or to set the lower boundary to zero perhaps? I couldn't find anything to tweak in configure facet display, or in other obviously related settings areas - I am currently continuing to try and find some documentation.
