Potential radar issue f15 baz vs f16c barak ii

Yesterday I joined an AirSB where several F15 Baz have been active, among M2000 and F16C. Interestingly, to my surprise, the Baz was always showing as enemy F15 on PD radar. I was not only one who actuatlly had teamkills. I scored two and I was 100% sure having locked a mig21.
Several people noticed that the radar was playing weired. Maybe a bug, maybe just a temporary issue.

because they propably use the same radar, as example the AV 8B+ gets shown as an F/A 18 on rwr because it uses its radar, they always show the main user of the radar, they cant differentiate between the different users
