Structs appears to display incorrectly in behavior tree nodes

When editing a behavior tree blueprint, if one of the custom nodes created and placed in the behavior tree has an "Editable" variable of a user defined struct type, then the variable's value appears to be displayed incorrectly when changed to something other than it's default value (it will be displayed as a large prefix of numbers and letters + the actual value)

1. Download the attached project
2. Open the project
3. Open "NewBehaviorTree"
4. Select "BtService_BlueprintBase_New"
5. In the details panel change "MemberVar_0" to true
6. Notice that the Node is not displaying a long string of characters followed by the word True

Expected: The text on the node would simply say true or false (NewVar0: True)
Result: The node says something like "NewVar0: (MemberVar_0FJFDAE42DFSDF34235ASDAFC =True)"
