Workflow builder Condition Editor is not working

[ZHANG Yan (SCH-CORP IT)]

Hi,

Recently our SAP system is applied new patch.
After that, workflow builder condition editor is not working properly.

I've tried drag/drop mode and classic mode to input the expression.
But no matter what container element I selected, it is not displayed in
expression1.

Any help on this is highly appreciated! 

Best Regards,
Zhang Yan
