Weird gearbox 5th 6th reverse

[nismo4x4]

Hey guys,

recently had issues with going into 5th 6th and reverse on 06 Man D40. Before the issue occured... I could not go straight across to the reverse "area" only the 5th and 6th gear which I assumed was normal but now sometimes it the stick goes way right across past the 6th gear area to the reverse area which isnt right...

see screenshot attachment

thanks in advance
