Changes to my in-game kits (weapons, gadgets, grenades etc) are not saved and reset after each game.

In a game I will change my kit such as weapons, attachments, grenades etc. When the next game starts or I leave and join another server, the changes I have made to my kits are gone, and they are reset to what they were before I made some changes.

For example, I went on test range and completly changed all my kits by changing the weapons and their attachments. I then played using each kit to ensure that the changes I made worked. I then went off test range and went back on again straight away only to find that my kits and been reset so that there were no changes what so ever.

Changes to vehicles are also affected.

Is there a way I can fix this? It is really frustrating to have to spend a few minutes of each game changing my kits to how I want them to be, rather than being able to just play knowing that my changes have been saved.

Please help.
