After compressing the experience of accessories, the experience of giving away is lost

In the test server, due to economic changes, my F16A accessory was automatically unlocked, but he did not allocate the experience of giving away each accessory level to the new F16C. I lost this experience and hope this bug can be fixed as soon as possible
Ps: My US Air Force technology tree has been fully unlocked, only a new F16C has been added and has not yet been unlocked
