Shop site displays different style and then instantly changes

Hi,

I am using your plugin and while I don’t really see many improvements yet on my website speed score I noticed some issues. In the shop when reloading the page a whole lot moves from one style to another, It looks like the actual style covers the standard Woocommerce settings and this really looks bad and doesn’t really instill trust into the clients. Is this because of your plugin and if so how could this be fixed?
