Host video not visible in recorded session

Hi. I have recorded a zoom meeting session

During meeting i had also shared my (host) screen for sharing ppt

During the session , I could see my (host) and others video 

However in the recorded session only ppt is visible. My (host)  video is appearing in some section and gets disappeared in some section of the recording.

Ppt is visible though 

I want to understand which settings to be enabled to ensure that host video appears consistently throughout the recorded version
