Website layout shifting towards right during presentation

Hello Community,
I am a beginner in Figma and I am designing a website. I am creating top Navigation bar with layout grid properties like 12 columns, 75px column width and 20px gutter size. When I am trying to preview a website it is shifting towards right as can be seen in the image below.
I have placed top navigation bar between these columns yet in presentation, navigation bar do not appear at center rather shifted towards right.
I would need your valuable advice to correct this issue.

The parent frame is bigger than that TV device.

Check your prototype device size settings. You’ll want the width to be equal to the width of your parent frame. If that’s not the issue then set your prototype view settings to “fill.”
