Boxster Shifter does not stop at neutral

[rene525d]

Recently I have noticed that all of a sudden, I felt something weird when changing gears. This morning i decided on confirming what the problem really was and here it is....

When say I am in 1st gear, then shift to second, if i try to put the shifter to neutral it just stays on the left between 1st and 2nd gear and does not go to the middle position. The same happens if I am in 5th or 6th gear, if i put the shifter up from 6th, instead of going to the default neutral position, it remains engaged on the right between 5th and 6th. Needless to say this makes it a pain to shift and can result in over-revving if i am not careful. Any ideas what the problem might be? I hope i explained myself clear.
