The Tenpin Bowling Association of Wales (Welsh: "Cymdeithas Bowlio Deg Cymru" ) (TBAW) is the national governing body for tenpin bowling in Wales. It is a member of the Fédération Internationale des Quilleurs (English: International Bowling Federation ) and the European Tenpin Bowling Federation – the "European Zone" of the World Tenpin Bowling Association.
World Tenpin Bowling Association when abbreviated is WTBA
As the statement says, when you abbreviate that that's what it is. I think the model was confused because it doesn't know how to abbreviate.
