How to add colon in a Message displayed if answer is selected

Hi;

 Is there a way to add a colon in a feedback message( using Quiz- question set) and H5P can interpret it as text, not as a command?

In fact, I would like to give feedback to the user when he chooses any answer.  So for example(Please see instructions below  for the quiz): I would like that when the user choose " Concentrate" as solution for the  "What do I need to do in my office?" he will get the following message:" Correct - From the text we can read: "my office is a place where I can concentrate""

When I have used the colon here " ...we can read : " my office..." the feedback stopped at the word was only: "Correct - From the text, we can read"

I have created an example here https://h5p.org/node/590267?feed_me=nps

What do I need to do in my office?

*concentrate::Correct - From the text we can read"my office is a place where I can concentrate"

relax::Incorrect -From the text we can read  "my office is a place where I can concentrate"

study::Incorrect -From the text we can read  "my office is a place where I can concentrate"

read magazines::Incorrect -From the text we can read  "my office is a place where I can concentrate

Best regards.
