I imported your listing here. The category states “Unknown” so it seems you had a category selected that is no longer available now.
After updating the category data once again you should try to re-select a category.
To update the eBay category data:
Open the GarageSale preferences > Accounts. Click on “Refresh Token” to refresh your eBay access token.
If done, select one of the listings in question and open the category browser. In that browser click on the sprocket icon to update the category data.
I also have this problem, for some time I can not upload any bags, it requires item condition for them, but the field was gray, so I couldn’t select any condition (it was on used before, never touched it). I forgot about the listings for some time, and now all the bags I had to relist are not in black (as not resisted) but are duplicates ready to be uploaded with all the item specifics and categories deleted?? Two listings of each bag, I didn’t make those?
