Personalized settings for "Project view popup menu" not working

Hi,

I'm developing a plugin for IntelliJ and I would like to reduce the number of menu for my users.

I did a fine tuning for the main menu and for the toolbar and it works perfectly on my users intallations. But now I did the same for contextual menu, for example for "Project view popup menu" but it seems not to work on my users installations.

It works perfectly on mine, but when I try the export and import procedure the contextual menu is exactly the same as before.

Can you help me understanding what is happening? Can be a bug?
