Eclipse - How can I change a 'Project Facet' from Tomcat 6 to Tomcat 5.5?

I have an existing Dynamic Web Application project in Eclipse. When I created the project, I specified 'Default configuration for Apache Tomcat v6' under the 'Configuration' drop down.
It's a month or 2 down the line, and I would now like to change the configuration to Tomcat 'v5.5'. (This will be the version of Tomcat on the production server.)
I have tried the following steps (without success):
I selected Targeted Runtimes under the Project Properties
The Tomcat v5.5 option was disabled and The UI displayed this message:
If the runtime you want to select is not displayed or is disabled you may need to uninstall one or more of the currently installed project facets.
I then clicked on the Uninstall Facets... link.
Under the Runtimes tab, only Tomcat 6 displayed.
For Dynamic Web Module, I selected version 2.4 in place of 2.5.
Under the Runtimes tab, Tomcat 5.5 now displayed.
However, the UI now displayed this message:
Cannot change version of project facet Dynamic Web Module to 2.4.
The Finish button was disabled - so I reached a dead-end.
I CAN successfully create a NEW Project with a Tomcat v5.5 configuration. For some reason, though, it will not let me downgrade' an existing Project.
As a work-around, I created a new Project and copied the source files from the old Project. Nonetheless, the work-around was fairly painful and somewhat clumsy.
Can anyone explain how I can 'downgrade' the Project configuration from 'Tomcat 6' to 'Tomcat 5'? Or perhaps shed some light on why this happened?
Thanks
Pete
