So I took the default t-shirt category and started deleting stock/ adding stock and generally changing content, just to test and all of a sudden the tax, visibility and status dropdowns decided to go blank.
This is when I choose All stores and is across all products/ categories even though I have only changed actual content, images, text, names etc in the t-shirt area.
Any clues?
Please don’t say that I need to re-install everything again!
