<br /> appearing in custom marker description

But i have another problem... when i complete a custom marker in "marker description", i tape "enter" after the first line, and write another line under-it, i click "edit" button...
I go on my member map, information in marker are ok, but, if i re-edit my marker, when i open i have the "<br/> code each line, and it's appear on marker description in member map, not good...
