Those entries coming from the Editor's official map are not working right. I'm sure Grapeshot messed it up and never fixed it. Some still show discovery locations for the old map and they are not there anymore.
Now I've tested my way and its working 100%
Look at the PowerStone and SecondaryStones. They are grouped together under the same PowerStoneIndex. The same way the old map worked.
The trenches doesn't have to be on the same block as the powerstone island. It is important to keep them grouped.
If you use an island then start with PowerStoneIndex 0 and the discovery : PowerStone1
For a trench use PowerStoneIndex 0 and the discovery : SecondaryStone1
You can name the island what ever you want. Also you can use any powerstone island with any PowerStoneIndex as long as you don't use the PowerStoneIndex or same discovery zone twice.
Well this worked for me and I hope it will help someone else.
