Merch Site Issue

Hi there,

I have an issue whereby the Merch site in the library is not aligning the sidebar on individual product pages to the right. It is showing below the description. In the example store, it shows fine, but after importing it shows as this. I am on Kinsta hosting, I just have the default plugins. I was at one point getting errors from GP and the Adv Woo Search bundled with Merch, but those have gone away and the issue has persisted.

Not sure how to fix this one, I've looked into the right sidebar and tried setting different priorities/hooks but that of course did nothing but mess stuff up further.

Thanks for any help!
