Just tested on a fresh install, to be sure it's not just wrong in my environment. But it happens on a fresh install too.

The behavior was correct if you set the datatype to accept multiple values, in that case you should always do a foreach over the results. But when configured as only having a single value we now return an empty string if nothing is selected.
