Contact Form Issues: Email has tab on each line

First off, the issue I’m having is on a contact form on my site here: https://www.roadscholarsmoving.com/denver-moving-estimate/

The form seems to look okay on the site, and the customers receive a confirmation email as they are supposed to. The issue comes into play when we receive the form on our email. On every line it adds a tab, I know my description of the issue isn’t great, so here is an example:

Does anyone know why when I receive the inventory form it looks like this? I’m a bit of a beginner when it comes to wordpress, so any help is greatly appreciated.

Thanks,

Zach
