Reply To: swatch not changing

Hi, i use an API to upload the same way as I always have I don’t touch the images or the titles or prices on the site they just go on to the site and when I use the mock-up like to use it now don’t work. On the top of the page I sent before the first 3 tees the wider-looking ones all work fine but I like the look of the slim tee. and now they have text that doesn’t change. link in private
