Hi there,

I’ve just run into an issue with segmenting by collections, one that I haven’t come across before. We’re integrated with Shopify and usually segment our audience by purchasing habits - so by collections/categories. However, I’ve noticed today that while all of our Shopify collections are listed as an option to filter by, there are also collections titled ‘collections:name’ which don’t exist in our own Shopify backend. After testing these, the ‘collection’ titles pull the incorrect data. Can anyone shed some light on what these extra collections are/why they exist? 
Thank you.
