Some text don't wrap when filling container

Why does some text wrap fully?

Changing from hug to filling container there is a line that could have been wrapped but ended up not wrapping.

This can be manually solved by putting the unwrapped text in it’s proper place if it’s a one off job. But when you’re dealing many pages then the work piles up.

That’s because your height and width has been set to hug.
Set the height and width of the text item to a fixed dimension you want so you can achieve the text wrap... effect.
