MX Brown strange spring noise coming from the switch

[Quteno]

Today I received my Durgod K320 Taurus keyboard, and I absolutely love it. It's such a quality upgrade coming from Corsair Strafe with MX Silent's. But while playing some games I've noticed that the D key is creating strange metallic spring sound, it's not squeaking nor typical ping (at least not what I could hear on youtube), but you can tell it's made by the spring. Makes me curious if it isn't a faulty switch, or will it get better and eventually disappear overtime time as the keyboard wears out slowly? Or maybe soaking the switch in some lubricant can fix this?
