What’s this # sign when using a H pattern shifter?

So I just received my Fanatec H pattern shifter from their Black Friday deal, during test driving I noticed that sometimes between gears it shows this # sign in place of the current gear on the hud. Does anyone know what it means?
For example, when shifting from 2nd gear to 3rd, it should go from 2 to N then to 3, but sometimes it would flash this # sign in between N and 3.
It doesn’t affect the gear change, but I’m just curious whether it indicates that I am not using the clutch correctly or something.
It does that, there is nothing wrong. I never paid a ton of attention to the timing of the gear number, N, and #, but I can tell you it has always done that and you needn't worry.
