Why Does Switching The Template of a Page To My New Theme Template Not Look Right?

HubSpot has an odd behavior where switching from one drag-and-drop template to another drag-and-drop template causes a sort of combination of the two instead of completely replacing the content with the selected template.

For Website and Landing pages you can use Content Staging to stage a blank page of the page you want to update to start fresh with the new template.

OR something that should also work for Blog Listings is:

1. Add ?developerMode=true to the page editor URL and hit Enter on your keyboard to go to the URL with the added parameter.

2. This will add a Reset Content button to each dnd_area in the Page Contents sidebar. Click that button to reset the contents to the template's original content.
