Hi,
1. Our variation swatches settings you can find in Theme Options > WooCommerce (Shop) > Shop elements.
Also, watch this video – https://xstore.helpscoutdocs.com/article/94-variation-swatches
2. If you want to use third-party variation swatches plugin then you need to disable our swatches module at all (Theme Options > WooCommerce > Shop Elements > Variation swatches > Swatches position > Disable)
