Gh3 Says No Lense Attached

[com21]

Ok so I just got my rikinon for my gh3 that i also just got and i started to play around with it but both in picture mode and video mode, it said "NO Lense attached, or record without lense in custome mode",  I herd this sometimes might happen, I checked that its right, put it on and took it off several times, nothing changed,   I got it to work by going to menue options and turning ON the RECORD  WITHOUT LENSE MODE,  now pictures and video work fine, all is good, But I just wondering why it would do that and if anyone have experienced it, I just got both of these products so it is all new.

thanks
