[Tex/LaTex] Wrapfigure apparently creating dumthe space on a following page

graphicsspacingwrapfigure

enter image description hereThe example below is a newsletter with two news items.

The first item has a wrapfigure to include a graphic. The second does not

But the resulting PDF (made with PDFLaTeX) has a blank area close to the as if the second item had a graphic too.

Any suggestions would be helpful.

Sorry about the extensive preamble – that's direct from the full document (which has dozens of news items).

Best Answer

The command \href doesn't start LR mode by itself. Due to how wrapfigure works (the details are rather technical), the appearance of \href in vertical mode blocks the reset mechanism of the special paragraph shape required for placing the figure. So the simple solution is

\leavevmode\href{...}{...}

See Function and usage of \leavevmode for some details about \leavevmode.
