Sometime swatches work sometime didn’t

Hi,

I’m using your plugin but if you take a look at my website performanceyarn(dot)com, you’ll see that sometimes swatches are visible sometimes are not, I need to refresh the page which is disturbing.

Can you please tell me how to fix this?

Is this plugin going to be supported?

Do you offer custom modification and fixes if you don’t want to support it for free as I really like your plugin?

Regards!
