Its unbeliveable the Warp drive disapears! It's a BUG?

Today I equipted my CV (from Blueprint lib) with the warp drive and tank. I filled the tank and started a warp journey from Akua to Masperon. The Warp works fine and after firing the warp I found myself in the Masperon Orbit. But at the same moment the warp drive has disappered !! I hope that this is a bug because it would be mad if the warp drive is as "single shot" engine and jou have always to build a new drive per one way Warp ride.

Is this a bug? Am I right or are you...
