Hi Ryan.
This is because you use some module in the right position. You should create a separate template style for pages where the left/right positions are used. In the current template style, the columns containing the left and right positions should be removed (in Layout builder settings)
Hi Mehtaz.
Your answer is not correct. This is a bug in Helix 3, when the left/right positions are determined and displayed in the code, even if the module is published on another page but not on the current page.
Workaround - creating individual template styles.
