Questie v.6.2.4 on WoW Classic 1.13.6.36935

When attempting to get mining nodes to appear on the map or the minimap, I am finding Questie cannot display them. Please see the below image.

In particular, I was looking to add Iron Deposits to the map so I could farm some. I tried to add it through this interface. It did not show them on the map. I was expecting to see marks in Dustwallow Marsh and Desolace. The interesting thing is, I can choose Dark Iron Deposit in this list and it shows me marks in Burning Steppes (and the item automatically pointed to that zone), but I turned on Iron Deposit and it says "Unknown Zone." Is there something that allows us to choose which zone to look at to make them appear? Otherwise, why doesn't this function work, which looks like it was built for this reason?

Update: I found that it IS showing nodes all over the map for Truesilver Deposit, as well. However, it does not show nodes for Iron Deposits and Mithril Deposits. I also noticed there are three listings of Truesilver Deposit under objects (I refined my search to just 'Deposit'). Two of the three show a zone when clicked on (one of them showed Dun Morough, which I was a little surprised of). When I clicked on them and chose "Show on Map", it actually showed them. There are also three listings for Mithril Deposit, but not one of them shows a zone when selected, which also doesn't show on the map when you try to get them to show.

Just thought I'd add this info after playing around a little bit.
