I am also experiencing the same issue. Do we know what is causing it, or what are the likely causes of this problem?
My problem with having multiple blocks for each paragraph is that the tab used to format the text in the block covers the other paragraph blocks. Some people may only want to focus on a paragraph at a time, but some of us actually want to be able to read over the entire blog post and would like to do that without having to click outside of the blocks. If there is a way to hide this tab, please let me know.
Actually, I figured it out. The options for editing have moved to the top middle dot, which is a problem when you file needs to be resized and that middle anchor dot is off the display! In future versions, can you move it back please?
