How to make my internal links to be ********

Hey guys

I have a site where I use Schema WP theme and Yoast Plugin for SEO. I just ran my site through a "Site Audit" on SEMRush and it tells me that all of my internal links are nofollow.
I assumed that default setting is do follow on internal links? How can I fix this?

Thanks in advance

p.s. I just noticed that forum software made this **** in the title out of what was supposed to be "do follow"
