When entering the ACM radar modes from TWS whilst having a pre-existing L&S, the L&S will be maintained as a 'ghost track' that appears at a fixed location from aircraft.
This Ghost Track will prevent the ACM modes from creating another proper L&S, essentially bricking the radar.
Track attached with neutral aircraft located off the nose with an aspect of about 150, crossing right to left, range 30NM.
NB, this bug is also exhibited with an L&S generated from RWS, track attached.
