Probably not. I would say sometimes hornet's radar works inconsistently. One solution you might wanna try is switch to gun then switch it back to your previous missile. I know it's odd but somehow it works. Kinda like reset mechanism of the radar.
I also noticed weird behavior of DL. How can my closer radar contact could not be shown at SA while the long range one showed at SA, both flying at high altitude (tanker and AWACS).
Our AWACS flying orbit behind me.
