yaml error in cloudformation template

[lincze]

i've just clicked on AWS Quick-Start Launch quick start url, and then wanted to see the template in cloudformation designer. it dropped an exception:

7/20/2020, 2:41:22 PM - Cannot render the template because of an error.: YAMLException: duplicated mapping key at line 944, column 7: RouteTableIds: ^

though, not really obvious why.

edited: the RoutTableIds definition is repeated (line 908 and line 944)
