What's the "Mid" on my F-14A's RWR?

It’s the only dot I ever see on my F-14A’s cheap af RWR that isn’t a “?”
It’s kinda annoying, and I unironically suspect the fr-nch to be behind this crap.

Anyone have any idea what it is?

MID is radar band from I-band radar and the “?” specifically on the F-14 is any pulse doppler radar iirc, dont quote me on that tho.
