Potential System, halp

I see your understanding of the system is wrong.

It works like this:

Using a Potential Scroll on an item that is not already "Unindentified" will MAKE it "Unidentified". There's no need to use the scroll on an "Unidentified" item. A magnifying glass is used to "identify" the item, which will cause it to gain bonuses. Note that using the Potential Scroll just ALLOWS you to use a magnifying glass on the item, nothing more.

Let's say the Potential scroll adds the potential to the item, but that potential is hidden (both the number of bonuses, the quality AND the state of the item: rare/epic/unique) a.k.a "Unidentified". Using magnifying glasses on the Unidentified will, well duh, identify that item's bonuses.

The CashShop redo things are just a scam which makes no sense at all except for how it works: allows you a chance to re-acquire new bonuse/qualities but NOT numbers.
