AX 4.0 error - A section in the report is higher than the actual page size allows

Anyone know what this AX 4.0 error means?  Looks like it is a sizing issue but I view POs all of the time so not sure why this one is a problem.

There is a ton of white space in the “Text” box on line item #2.  Someone needs to go into that PO on Line #2 and delete all of that empty space for the document to generate properly.  All of those extra spaces is what is causing the document to throw the error.
