Can't access system analysis diagrams from Workflow page

Hello,
I recently migrated my project from Capella 1.1 to Capella 1.2. When i try to create a diagram from the workflow pane, for example i want to create an LAB by clicking on Logical Architecture on the the workflow pane, nothing is displayed. See screen shot attached for more details.
Thanks in advance.
