I think this may be a technical issue. I am having a problem finishing my design to sell it, when I click on my designs it does not show up, also there are other designs that aren’t even mine. I have two stores and when I click on my products it opens up in the store that I am not working on.
@akacruiseman unfortunately, I’ve also come across these glitches before, too. I sympathize. doesn’t appear to be a fix. 
Same thing happening today 06/05/2024. I am designing save the date shot glasses and this is the second time it happened. Could it be that type of particular design?
