from what I can see JimmyZ doesn't seems to be on a table (maybe they set their option to not be "observable"), jesse.m.frey is alone on a table, that's right.
I don't understand what exactly the problem is.
If you are concerned about not being enough tables available to play for others, then this is not a problem. Virtual games don't have the same space restrictions than brick and mortar places, the number of tables isn't limited (or likley not by a number where 2 less is noticable).
If they are your friends and can't play because they can't leave the table, then they need to open an incognito (Chrome) or private (Firefox) window, go to "dominion.games", enter their name and password, but don't click on login but on "Kick & Resign" (small text below the login button). That "frees" them from whereever they are trapped in. Then they can use a normal window and login again.
If it is something else you are concerned about, please explain.
