Varation swatches not working properly

Hello,

I bought the woocommerce product variation swatches from your site. For some products when i try to set a preload for the variables e.g size and colour, i notice that the size disappears, leaving only the colour variation.

Moreover, while the variations swatches global setting was properly done, only products from a source shows images, products from other APIs were showing button instead of images as set in global settings.

Again, both the plugins; variation swatches and muticurrency switcher keys cannot be updates. It shows fatal error is on my site. I contacted the host company, all errors corrected but website remains slow giving Error 524 and inaccessible.

I will appreciate a response.

Thank you.
