Can't see Heavensward ephemeral nodes.

First, I found that I had not read the regional folklore books, so I bought them in Idylshire and used them. The folklore books now show up in the gathering log, but I still can't see any of the nodes pop at the specified times and locations.
I've tried gathering nearby regular nodes, restarting the game, but still nothing appears. I've tried Dravinian Forelands, Churning Mists, and Sea of Clouds. Nothing.

Just to prove to myself that I can see them elsewhere, I went back and gathered them a few Shadowbringers zones without difficulty.

It's been some time since I've enabled ephemeral nodes in other areas, so am I missing some other unlock action?

Here's the folklore entry in the gathering log:

Edit: I did find one in Sea of Clouds using this site: https://ffxiv.consolegameswiki.com/wiki/Ephemeral_Nodes, where they list 4 locations for SoC:
X:26 Y:35
X:23 Y:12
X:13 Y:18
X:15 Y:22
It was at the last one. All the other zones only have one location listed, and I haven't been able to find anything at any of them.

Ephemeral node locations were changed when the gathering collectable system was changed in Shadowbringers. I don't know if the wiki information was ever updated.

I tend to use https://garlandtools.org/bell/ for all timed nodes. There are some other tracking websites with node information as well.

As a side note, what you're displaying are Legendary item not Ephemeral items. Ephemeral items are listed with the normal gathered materials and will have the Collectable symbol next to them. Location will be displayed on your map then time will be added to the log once you've gathered an item for the first time (same as Legendary). Collectables for Custom Deliveries are also listed with the normal items while collectables for Splendors are listed under Collectables.
