InDesign showing missing links to page that doesn't exist

1. Create a new document, without ANY STYLES.
2. It has to have 2 pages, same size, same bleed.
3. No additional layer, rename the existing layer to “OLD LAYER”
4. Save this document.
5. Open both, old and new document.
6. In the new document: Layout > Pages > Move Pages … from old to new,  add at the end
7. Save
8. Delete the first 2 pages from the beginning and the “Old Layer”
9. Save as INDD

It should contain only valid items and end up with smaller file size.

try to export to IDML, then open it. will it make a difference?
