WebCam present problem in recorded video in BigBlueButton

I need assistance in integrating BBB into my LMS system. I configured the layout to build the recorded video as follows when the screen and webCam (1) are shared at the same time during the recording process.

bigbluebutton\record-and-playback\video\scripts\video.yml

layout:  width: 1280  height: 720  framerate: 24  areas:    - name: presentation      x: 0      y: 0      width: 1280      height: 720    - name: webcam      x: 0      y: 0      width: 1280      height: 720        - name: deskshare      x: 0      y: 0      width: 1280      height: 720          pad: true          - name: webcam      x: 960      y: 500      width: 270      height: 200

When using this layout, if both the screen and webCam are shared during the recording process, the video is recorded in the same structure as screen1 as follows.

When using this layout, if both the screen and webCam are shared during the recording process, the screen sharing layout (full-screen) and webCam layout (small) are displayed in the video like the screen1.png file.

However, even when screen sharing is disabled, the webCam layout (full-screen) and webCam layout (small) are displayed in the video like the screen2.png file.

I don't want to present a small webCam layout in this case.
