I'm using QGIS 2.8.4 and I can't seem to figure out adding more than one legend to my Print Composer. Say I want a larger map and then an inset map -- showing perhaps a different classification/color scheme -- on the same page of my Print Composer. For whatever reason, despite checking the lock button(s), my "locked" legend will change according to whatever my original Q map shows. Therefore, if I want to add two legends, I'm really just adding the most-recent one and duplicating it.
I've tried every possibility of the locked buttons/cache/etc.
