Fixed for the next update
there is no actual box titles you will only add a image and url ( up to 8 per block ), the title you are seeing in that image is the overall blocks title and they are not required
The problem with this is unlike the forums it uses the title and some text of the topic, when you use that setting on the forums you are only seeing the title and none of the topic, if it is a topic with only a few words then the whole topic is in view for members who can't read them
