Block editor always opens the same product page

Hello,

When I open (any page) with the classic editor, everything is fine.

But when I open the same pages with block editor, it shows the content of a product page! It’s always the same product page, no matter which page I try to edit:

https://wellness-lagoon.com/product/6x-taisho-counterpain-balm-red-120/

I tried several things:

Opening with classic editor and then on the editing page, right sidebar “Switch to block editor”, the same happens, it switches to the content of that product page (see link above).

To see what happens, I made some changes to that page, (and es expected) that product page has been changed, not the page I originally opened.

I also added a new page, called it “Test” and wrote in the content “test”, nothing else. When I open it with block editor, it opens that said product page.

It actually always shows the correct url and the respective page-ID of the “PAGE” I want to edit, but the content is from that “PRODUCT Page”, and when I change anything the changes occur on that Product Page as well.

I de- and re-activated all plugins and it this bug only showed when “WP Product Gallery Lite” was activated (and everything worked fine when it was deactivated).

Can you fix this? I’d like to keep using your plugin.
