When you have a newline in value, the project listing page shows 0 completion for that project

When you have a newline in the value, like this:
...
"show_previous_work_message": {
"value": "Tu trabajo en el "Paso {0}" fue
{1}",
"description": "The message that shows the step number and title and the work from a previous step."
}
...

the tool shows 0 items completed.

I think the reason why this happened was because the english text that appeared for the translator was:
Remember, your work from "Step {0}" was
{1}

There is
after the word "was", but this was not shown to the translator. So the translator copied and pasted the english text and translated to spanish.
