Blank title still generates empty container

Hi there, I was using your plugin for map of our republic which was wide as 100% of the widget area. After last update (after few months) I have also updated the image of the map, added new hotspot and saved. Probably since that the map is smaller with the container on the left with the Title (Before fully without title which is what I need). Even when I delete the text in the title, the empty container remains. Could you please advise me how to get rid of it again? Thank you, BR Martin
