After adding new parameter to an operation through the properties window, it's reverted back to Unnamed and default to
type "int".
- create and name a class from the project tree or diagram
- add and name an operation in the class
- select the operation and click on parameters' '...' button to bring up the parameters dialog
- click on New Parameter to bring up the New Parameter dialog
- enter a parameter name, eg, p2, and type "double" and click OK
At this point, it shows p2 of type double in the Parameters dialog ok for the operation
- click on Update (this is an optional step) since it's new parameter but just do it to make sure
- click on OK button to dismiss the Parameters dialog
Result: in the diagram or project tree, the newly added "p2" parameter is now displayed as "Unnamed" with type "int"

Workaround: change parameter and type again from properties editor or change them from the diagram
