Zoom Recording while sharing screen issue

I was recording a Masterclass and was sharing my screen.  Every once in awhile I would pause the video to look at my notes and when I unpaused the video and kept going everything seemed fine.  But when I went back and watched, every time I paused the video...a black screen was inserted for a second until I got started again.  Is there something in the settings that is causing this or is it something that happens when screen sharing and pausing a video?  Thanks for your help.
