ADAU1461 INPUT 9 bug in SS 3.8

Hi.

When trying to use input 9 (TDM ch 8 on the ADAU1461) in sigma studio3.8  i get an error on compile download.

"Error in Input1

Line Numer 30

"digin_9" variable used is not defined in RAM or not a RAM directive."

If i go back to Sigma Studio 3.2 it is OK.

Is there a Fix for this?

Thanks

Brett
