After Publishing a new Landing page with Schedule block one entry from Full list is lost.

Steps:
1. Create a new LP.
2. Add a Schedule block.
3. Keep adding content items each time moving the slider into the future (in this example 4 items).
4. Verify the Full list in Edit mode (before Publishing).
Result: 4 items are airing. [OK] (screenshot 1)
5. Publish.
6. Verify the Full list in View mode.
Result: 3 items are airing, first one is gone [NOK] (screenshot 2).
(when returning to Edit mode also 3 items are displayed)

Remarks: Occurs on master.
