Since the introduction of support for different captions when multiple maps are utilized, an issue has been highlighted.
Some infobox templates use their caption parameter directly instead of passing it to this module. This results in the display of a "##" between the two captions.
If you are unable to edit the infobox template, contact Bellezzasolo.
