Default Select Option when using Listo

I am using Listo to display a list of countries “data:countries”. After upgrading to 5.0.3 or later, the default option no longer works. The first item in the list is selected instead of the default one that I choose.

If I have a manually entered list of options, then default works as it should. It is only when using Listo data that the default option does not work.

Does not work: [select* dealer-country default:235 data:countries]
– Aruba is selected, which is the first item in the select field

Works: [select* dealer-country default:2 “1” “2” “3” “4”]
– 2 is selected

Thanks!
