Stream Theme customization

Oh I get what you mean!

Is this what you see as well?

That's completely normal!

So for this part, it's generated by a plugin called wp show posts, and you'll be able to edit it's format at Dashboard > WP show posts.

For the email subscribe part, it's generated by another plugin called Mailchimp, you can find it at Dashboard > MC4WP > Forms.

Basically if you see anything with a code, it's generated by some plugins, and you'll need to edit it in that plugin.

Hope that helps :)

Thank you so much. This is a huge help. Sorry, big learning curve for me. I have enough to continue with now and thanks again for your help.
Kind regards
