IDz User Build Error Feedback

Hi, I am trying to set up the User Build error feedback mechanism. 

I have followed the instructions to do this, i.e. including the compiler option: ADATA,EXIT(ADEXIT(ELAXMGUX)).
However, when I run a User Build, the Remote Error List view is automatically made active but the compile warnings and errors do not populate in the Remote Error List.

If I execute a Remote Syntax Check on the same source member, I do get the error feedback in the Remote Error List.

Is there any additional setup required to get this to work?

We are using IDz 14.0 with RTC 6.0.4
