Found the table button – it looks nothing like what is displayed in the online tutorials. Clicked it and received an error: “Cannot set properties of null (setting ‘value’). Still can’t add a Swimlane. . . .

Hello, I want to add a swimlane to my chart. The online tutorials say to select the entire Pool, go to Arrange tab and there will be a Table button to add the lane. I am in v 28.06 and see no such button, screenshot below:

I selected a pool using desktop 28.0.6 and clicked insert before and it works correctly. Are your steps different?

I did the same steps, but received this error: “Cannot set properties of null (setting ‘value’)”
