Profiles changing names and multiplying

I need to use some own created profiles in the 66i.

I do set up all as needed and then create a profle, edit its name and make a bakup of it by connection the 66i to pc and exporting this profile to my bckup server.

So far OK.

When I set up 66i, I copy my needed profile to the profiles folder on the 66i, then I go to profiles and select it and say: use from the menu

And now troubles start. Very soon I have in the list of profiles this one let say 5 times. Often I get profiles with older name, used few months ago. It all behaves without any logic, often the surplus profiles can not be even deleted from the 66i, only when I connect it via usb cable to pc and delete all self made profiles from the profiles folder.

Does someone has the same experience?
