RDP AutoSize not working

Hello,
We have version ASG Remote Desktop 2016 (9.0.5385.0)
and the AutoSize does not seem to be working after I reinstalled on Windows 10 (1607).

My monitors are at 1920x1080 but the RDP sessions do not scale correctly.

RDP sessions in mstsc.exe work\scale correctly.

I have to disable auto size and manually put in a resolution to work for now.

Is there a work around or fix for this ?
I haven't come across anything yet in the forums.

thanks
