Welcome to OpenStreetMap and thank you for your good work improving the map.

I notice the "opening_hours" on Royton Leisure Centre at https://www.openstreetmap.org/node/10622234073 looks like it's missing a "0" on the end: "08:00-17:0" probably should be "08:00-17:00" but let me know if I've jumped to the wrong conclusion.
