Problems when using XLIFF plugin parser with Trados 2014

My XLIFF parser plug-in is being properly added to Trados 2014 in the Add-Ins. When loading the project settings I can see the link that detects the plugin and I add it to my list in File Types. I disable the default XLIFF file type. Then when I create a new project and add an XLIFF , the file type that Trados uses is still the default XLIFF and none of the breakpoints in my debug code are working.

I noticed that as a workaround, if at the window of adding project files I click on the File Types, there is again the link that I previous added and I repeat the steps above again. At that point, Trados loads the XLIFF with my file type.

It looks like the initial step of adding the file type is not being applied. Please note that I am using CU3 Beta.
