I'm a danger to myself and my training log

I was trying to input a table from a challenge I am doing into my short term goals and somehow I ended up with the whole darn forum page instead.  Now I can't seem to remove it no matter what I do, whether it is trying to select all and delete, go into the html editor to select all and delete, cut and paste into another document, etc.  I can't even seem to delete the goals I had in there as pure text prior to my pasting "incident."

For whatever reason, everything seems to reset after I hit apply.  I really just want to remove the whole thing, if I could.  Any help or ideas for this newbie who knows just enough to be dangerous to himself?

This is my log:
