Has anyone seen diagram layout problems like this before?

Hi all 

I use Cameo Systems Modeler 2024x on both a Windows machine (Refresh 1) and also a Mac (Refresh 1 HF1). 

I've some strange layout issues today, most notably with the Diagram Info, which I am struggling to find the root cause of. Windows machine displays it correctly, the Mac does not.

I can't tell if it is a tool setting or config or indeed a bug.

On the windows machine the diagram looks like this:

On the Mac is looks like:

Has anyone experienced anything similar? If so is there a tool setting or configuration on the Mac that I need to change to resolve?

 

Thanks in advance.
