Actually there is something I don't quite understand. By the way, this is all happening in the grid labeled 'Evernote".
OK, so some of the items just disappear when I restart SN. So, I'm looking at the filled fields for the items that work. Some has "ItemhasHTML" checked, some have "Evernote" checked. (They all have something in Item).
Now, why they don't all have "Evernote" checked is confusing to me. They were all entered in the Evernote grid so they should have it checked automatically when the item is created. Actually, I'm noticing that all the top level items have "Evernote" checked and the lower level items do not.
Now about the 80-something items that keep disappearing. All except one do NOT have "Evernote" checked. All these items were created in the Evernote grid. I would have expected the default behavior is to have the grid name field checked when items are created in that grid.
Again, remember, I don't ever touch the source box or do anything with filters.
