Why are items on my website store not showing in the categories they are assigned to on my dashboard

[terrisg]

I have MANY items that when I look at them on my dashboard they have the correct categories selected.  However, when I just go into my website as though I am a customer, there are many items that are not showing up when I try to shop by category.  As an example, on my dashboard, a particular category will say "60" items, but when I try to shop by that category it only shows "40" results; which means that 20 of my items are not categorized on my website even though they are on my dashboard.  Emailed Square, but of course no response.  To fix this I have been going into my dashboard items, one by one, and verifying against my website store.  If the item doesn't show up in the proper category then I am going into the item on my dashboard, deleting the categories, saving, then re-entering the categories, and saving again.  UGGGHHH.  Anyone know why this happened?  Anyone know a good way to fix this?  Anyone know how to give Square a good piece of my mind?  Thank you in advance.
