ARIS Connect does not show ORG models

In ARIS when I create an Organizational Chart, I am unable to see the Diagram in ARIS Connect.

I can see the model in the tree in Connect but when I select the model, the Diagram option is not present, all I can see is Overview.

This is an extract of the URL visible in Connect showing model type   -   ./#default/item/c.orgChart.

This does not affect other ARIS model types, and within ARIS itself the model appears to function normally.

Other users and ADMINS are affected.

Is this a configuration issue in Connect and how do I access configuration if it is.

I am working in ARIS Architect and Designer 9.6

Thanks in anticipation
