Hello @Dawnthompson728 thanks for your post. Please read this post for more info about this topic. I suspect it may be those items on your website may have been inadvertently marked as Unavailable. Please note that if you do not have sync turned on between your item inventory and items on your website, this may happen.
You can also make sure newly imported items are automatically marked as available by clicking Settings > Square Sync and checking to make sure the toggle is off for Mark newly imported items as "Unavailable" online.
