Need help removing 'Dr' prefix from a list of names without causing an infinite loop.

have a list of names which proceed with 'dr' which I am trying to remove with a formula {{Name}}?.replace("Dr", "") but Clay is saying this is causing an infinite loop. Please advise. https://app.clay.com/workspaces/206158/tables/t_Ab6Ub4Be5k3Q/views/gv_1lqG6XXCbQxD
