“Read more” turns into “Follow me”

Hi,
I have inserted the read more tag into several of my posts, and on my blog page it displays nicely after the excerpt like this:

[Read more]

However on each category page instead of saying [Read more] it says “Follow me” and it isn’t even a link, it’s just plain text. Why is that? I would like it to display like on the blog page, and if possible edit what it looks like/says.

I’m using the Zuki theme.

Best regards
