Problems with the Supermenu in Elements Kit

After creating a Mega Menu using Elements Kit, I am experiencing a problem with a blank sidebar on the right side of the page, after disabling Mega Menu the page returns to normal width and the blank sidebar disappears. I have tried checking and adjusting the Mega Menu's width setting, page layout to full width, and disabling other plugins, but the problem persists. May I know how to solve the problem of blank sidebar on the right side of the page after enabling Mega Menu?
