Error querying region objects in DataBrowser

I'm querying region objects that have fields of type List<String>. I can successsfully perform the following query:

select * from /myRegion m where m.Name='objectName'

However, when I execute this query:

select m.someListOfStrings from /myRegion m where m.Name='objectName'

I get this result:

What is the problem here?

Thanks!
