No 7th in sport plus?????

[Martingale]

As title indicates, I cannot shift into 7th gear in my 987.2 Cayman S (PDK) whilst in manual mode when in sport plus. Works in normal sport mode.

Is there a reason for this or something wrong with my transmission??

Thanks for the insights, but does that not mean my top speed is compromised in sport plus if I'm a gear short?
