Online store when accessed from facebook shop showing wrong items

[DeliVolv]

If you follow my progression of screen shots you'll see how I ended up on this page.  It shows items that are not intended for my online store but are in my on-site POS system.  Is there a fix for this?  I would like it if my customers could not reach this screen.

Update:  I tried deleting items on the "Order Online" subdomain, but that deleted the items from my in-store POS system.  Then I tried setting up a redirection from "delivolv.square.site/s/order" to "delivolv.square.site" but this only works when accessed directly; if you follow the progression of links in the OP you can still access my in-store POS system.  

Any Help? I'd like it if my customers could not access my POS system.

So for some reason the redirect works only for mobile, but on desktop you can still access this screen that shows all these extra items.  But I found out how to turn them off without deleting them from my POS, If you go to your items on your POS screen, you can individually select "show in online store" for each item and toggle it off.  IDK why these were added to my online store (maybe it happened when I synced and I just didn't realize that there was another page other than the main page).

Hope this helps someone else.
