We are currently testing our new SP 2019 environment with Nintex forms & workflows. We were able to build both form & workflow and run test. The problem now is we are not able to view the Nintex Workflow history associated with an item or for the running workflow. It only shows up to where the red line or arrow. No scrolling bar showing or expanded button displayed to view the rest of the workflow to see the path it's taken.

Appreciate any help on this.
