HELP with removing archive wording

I have a custom theme so not sure anyone here can help. I am a bit familiar with cSS and have customized themes.

What I want to do is, is when you click the name of a category from the sidebar widget, the post shows, but directly above the post it says ‘archived for the whatever category’

how do i find this in the editor so I can remove it.

I do not want it to reference the category at all. Just show the post.

Thanks
