Relationships Window showing incorrect Stereotype

[ihodgetts]

I have a deployment diagram showing a number of artifacts showing a mixture of dependancies, usage and deployment. One of the artifacts shows one such link as <<use>> on the diagram, but when double clicking on the target artifact itself, the Relationships Window shows the same link as "deploy". In fact, if you then right click on the link in the list and show it's properties, the stereotype shows as "use" (not "deploy").

I can delete the link (from the Relationships Window) and then re-add (as "use") on the diagram, but the link still insists on showing as "deploy" in the Links tab.

I thought a "deploy" link had to be from an artifact to a node? In this instance it is from one artifact to another artifact. The only difference I can see is that the target artifact is from a different diagram (I dragged it as a link).

Any ideas why I'm getting this behaviour?
