Yes, the droop on one side can be causing the issues. The RR Sport air suspension should be put into tight tolerance mode when doing wheel alignments. This will allow the vehicle to be properly aligned. You will need a Land Rover specific diagnostic tool to do this, ie. Hawkeye, Faultmate, etc.
Also, make sure your mechanic is using the latest alignment specs from Land Rover.
