Content from an old template in revisions showing up

Hi
So to start off with wordpress and woo is very new to me.
Currently moving from one ecommerce platform into wp/woo and starting to get a hang of it a bit. I thought.

Tested search in my local setup and noticed results with copy “Best Quality Products We Print What You Want! ” I had not written, noticed/guessing it comes from an old template that I might have tried during my testing that is no longer installed as far as I know.

Went to edit the pages I found this on but that text/copy is clearly not there. Went into phpmyadmin and searched and found more or less all pages and the products having this copy/content but in siteurl/1905-revision-v1 and 1905-revision-v1 is for all the different posts/products/pages.

Post parent: 1905
guid: siteurl/1905-revision-v1
postname: 1905-revision-v1
post_excerpt: Best Quality Products We Print What You Want!
post_contenct: Best Quality Products We Print What You Want!
post_type: revision

So can anyone point me in the right direction here on how to fix this?
Is it safe to delete all these posts from phpmyadmin or can I clean them in UI somehow? How do I make sure this does not happen again?
