Find Multiple Hotspots - problem with creation new content

Hello, I have a very strange problem when creating new content in Find multiple hotspots.

When I create new content and in the editor I choose the type as Find Multiple hotspots. Everything looks ok but in the hotspots tab in place "choose approprate figure for your hotspot, configure it, then drag and resize it into place." Instead of a square or a circle there are two black dots as in the attachment I can't add active points in the image. In a single Find hotspot is ok.

Please help me :)
