Feeds are showing where Post archive page should be

The problem:
Archive/category page is showing up as a feed.
https:// site-example.com/show/ shows a feed instead of posts.

Details:
Updated WordPress to 4.8.
Everything else is updated.
The links must stay the same.
There is a feed with the same title at:
-- https:// site-example.com/feed/show/
Using wp-forge theme with a child theme.

What I've tried:
Created a template with various names as per the Codex.
Disabled and removed all plugins and themes.
Deleted and removed cache plugins.
Disabled all feeds.. those 2 are still showing up.(/feed/show and /show)

I'm sure someone will have an answer already for this.
It can't be a new issue... I'm just new to feed management.
Thanks in advance for any help! :)
