Event not showing up online

[APD_art]

I am trying to add classes (in person at our art store) to sell through my square online site and with our POS in store. On the website the test classes only show up if I enter them as a physical good in my inventory. I tried making a test as an "event" item and also "other" in the class category but neither shows up online. The only one that shows up is the "physical good" test item. Classes are not taxable, physical goods (art supplies) are, so I am trying to keep them separate. Has anyone gotten a non taxable event to show up as an item under a category online or have suggestions on how to organize this? Everything is selected to be visible and on the site. I found someone discussing this exact problem on here but the discussion had been closed. Thanks for any tips!
