How i can edit LW options? Such prefix in chat like [littlewigs]?

Trying /lw, /littlewigs, /little - but with no luck.

/bw to open the main BigWigs options then click on the "Dungeon Bosses" tab

Ohh. IN BW I don't see any option to setup Infobox (Locking for example) and cant remove [Littlewigs] prefix whent addon posting in chat.
