Porsche Cayman GT4 CS MR not Auto Downshifting

I have Auto Shift on. The Cayman is not downshifting. I don’t know what other cars (if any) have the same issue. Am I the only one seeing this? I have a G923.

 

Not downshifting at all?? So it gets to 6th and stays there?

 

Not downshifting to the proper gear(s). Doesn’t have to get up to 6th gear. 3rd or 4th gear negotiating tight corners is wrong. I have to use the paddle shifter behind the wheel to manually downshift.

Switched to another GT4 car (McLaren) and did not have this issue.

 

Keeps hanging in 3rd or 4th gear, doesn't go to second in slow corners.

Thx it's reported

I need to test the other Cayman (Clubsport) but not sure if I will get time today. I ran a practice session with all GT4’s yesterday. After about 30 minutes before I quit I checked the timing and ALL the slowest times were Caymans. So maybe it’s a bug with the AI controlled Caymans too?
.

 

The other gt4 Cayman is fine.

 

I filtered out the Clubsport and just had the MR's for another short practice session. Is it a coincidence that all but one of the slowest times are the Caymans?
