Only one newline allowed in a label

[jon-j-warren]

In a treemap, I'm trying to insert a label with 3 lines of text: the Name, Value, and Share.
When trying to separate the 3 with the newline character '\n', it works only for the first time I use it and then it does not work later in the same string.

Here is a jsfiddle of the problem I'm having:

While I'm on that topic, is there any way for me to remove the Share % from the bottom?
