Change your buttons OnSelect to UpdateContext(varShow:Open}), UpdateContext(varShow:In}), UpdateContext(varShow:Awaiting}), and UpdateContext(varShow:Closed})
Make the Items property of your gallery:
Switch(
varShow,"Open", Filter(Ticket,"Open" in Status.Value).
"In",Filter(Ticket,"In Progress" in Status.Value),
"Awating",Filter(Ticket, "Awating Information" in Status.Value)
"Closed", Filter(Ticket, "Closed" in Status.Value)
)
IMHO, the buttons are clunky, an alternative that I have used is even easier. I would put a radio control on the screen with Items property ["Open","In Progress","Awaiting Information","Closed"].
Make the Default property of the radio control Blank()
and set the gallery Items property to
Filter(Tickets, IsBlank(Radio1.Selected.Value)||Status.Value=Radio1.Selected.Value)
