Error with content editor

Hi. I take several weeks trying to somehow fix a problem with this plugin. I tell you : Apparently , until not long ago , the entire contents of the rows that I created in an accordion, could develop with the text editor WordPress , very comfortable , because I was able to insert objects or other elements that gave greater showiness the accordion . However, now only it allows me to do that in the first and not the rest . Why does this happen? I appreciate it that only you could me explain. Greetings.
