Hello,

Currently you are using “Icons on hover” style for your shop grid. When I select some other styles then your color swatches shown perfectly fine when I click select options.

For the homepage you need to edit those sections where you used products and then change the product style to inherit or also choose some different style except of the icons on hover which is currently selected.

Best Regards.
