Adding existing file does not work

I have not been able to add existng files to a project in AppCode. This started in v1.x and continues in v2.0.

If I right-click on the project in the Project window and select Add->Files, I get a Finder window to choose a file, but after choosing, the file does not show up in the Project window and is not added to the project. I have to add the file in XCode in order for it to take.

It gets even worse in v2.0. I used to be able to right-click on a group within the project and at least get a Finder window to add files - now nothing happens when I select Add->Files.

I am using the Perforce plug-in. I've tried checking out the project file in P4V, but that makes no difference.

Any help on this would be appreciated.
