Changing Page position for listed pages shows hyphen in panel dropdown

[RM1234567890]

Description

When I want to change the position of a listed page, the numbered options in the panel dropdown includes a hyphen as the first option that can be selected, please see first screen shot.

If the user selects the hyphen instead of choosing a number, it throws an error, please see second screen shot.

Expected behavior

No hyphen should show up as an option when choosing a position for the listed page.
