Bug: Only 10 timelines in the dropdown menu at Edit page

If you create more than 10 timelines, the least recently used are not shown in the dropdown menu in the Edit page.
In this instance I have 11 timelines but can only see the 10.
Screenshot attached.
Suggested solution: Show all timelines created.
