Hello,
1. ” it still shows the background color and not the image.” Please follow this instruction to solve this problem: https://xtemos.com/docs/woodmart/variable-products-swatches/
2. “Shows White as #FFF instead of the image” I do not see the problem: https://gyazo.com/8a7016e9785bcf94620cf7078a1ad860
3. other issues from #232730 make sure all the variation have the image.
#232732
First of all, you add attributes to the product, then you choose what variation should be created. If you can choose S and M for the red color and cannot choose the 4XL it means that such variation does not exist cause you have not created it.
The filtering works in the same way: it sorts our existing products.
Best Regards
