Removal of rectangle from captivate 2019 recorded slide

When I record a video of an application in Captivate 2019 a rectangle is located within the video. This is doing nothing and I cannot find out how to remove it. This was not there in earlier versions of Captivate. I need to full slide in my video but the rectangle covers part of the application window. I have included part of a screen shot. I cannot find the switch to turn this off.

Captivate 2019 cannot import PowerPoint 365

I have been unable to import a power point 365 into Captivate 2019. Is there a reason for this? Is this function not possible? I have had to save the presentation in an earlier version of powerpoint to get it in to captivate 2019
