Unable to update WADL from Swagger with 5.5.0

Added a WADL to my project using ImportSwagger option. After few months a couple new methods have been added by devs. Clicking on 'Recreate WADL' button on the service viewer is not updating the new methods to my project. 

I can not delete it because soapui prompts saying its going to delete all the associated steps.

What can i do now?
