Hi! I'm newer to marketplace and I have shipped 4 items so far with no issues! But now when I make a new listing and add the shipping option I can't choose the item weight, it is just a preset price that I cannot change. I'm not sure why this is, I used to be able to select a weight, now I cannot. I don't want to list anything new as I'm worried the preset amount won't be right for the item. Thank you to anyone who has answers!
