@Smart-Communities, I think you need to edit your short bookmark and re-select your reboot command.
I suspect maybe you renamed your computer?
I just did that - I added a space between New and Laptop. It made my short bookmark red because it no longer matched the computer name:

Then I fixed it by editing my short bookmark and re-selecting my reboot command:

About your idea to have the ability to view all standard and short bookmarks - it's not possible to show the standard bookmarks because they're not stored in the database. The standard bookmarks use a JWT, which is what makes them so long.
