Can't change paragraph style -- is this a bug?

Hi, all! I've run into a problem I can't seem to solve. It seems to happen when I've inserted a table. Essentially, the paragraph mark closest to the table seems to have its own paragraph style so that, if I click delete or backspace (where the paragraph mark is at the end of the previous paragraph), it changes the entire paragraph to the new style.

If I try to change the paragraph back to "Body," nothing happens. This has turned into a problem because I occasionally find that I have a space between a paragraph and a table marker (usually when I'm working with conditional text), and it seems impossible to simply backspace/delete to get rid of that space.

It's a littler hard to explain so I've made this video. Unfortunately, I don't have access to a microphone at the moment, so I've tried typing each step within the video. I hope it makes sense. If you need more information from me about the problem, please let me know. Thanks.
