Cant add prefix to each string in the list. It gives me only one

Greeting!
Doing my first steps in dynamo, but can’t understand how to solve this problem.
I have created a prefix from project information. But when im trying to add it to each string, it creates only one.
When i do it with code block and random text it works well, but with my information project string not.

Hello @daniils.klekers and welcome to the community, try something here…

It works!
Thank you:)
