New member, first message, long time OpenOffice user

First off, let me boldly state the following that I am sure many of you can concur with: I AM SICK AND TIRED OF MS WORD! Thank you to everyone at Open Office for their time in making your AMAZING FREE OFFICE SUITE!
I haven't done much work with tables until recently, and I have come across a slight glitch (user incompetence)

I am using the most up-to-date Writer 2.3.1. Please review the following two screen shots: You can see at the Red arrow there is no space, but at the Green arrow, there is a space. As you can see this is part of a List and I am using tables to get easier control over different levels of sub-lists.
I don't know how to remove the space below tables at the green arrow. I have tried everything I can think of... My document is rather long with a lot of short lists and these added spaces taking up a lot of it. As for the tables above and below the Red arrow, I don't know how it did that! I have gone through many menus and I can't figure out how to get closer to the table below it. I think the tables in the Red arrow are corrupt somehow and somehow the space below that table was accidentally replaced or hidden.
My Question: How can I eliminate the blank space you see above the Green Arrow beneath all of my tables? Delete and Backspace just erase the entire table or break out of the List!
Thank you very much in advance!
