Simply moving a basic title to later in the timeline

Hi - I will start off by saying that I am rather embarrassed to post this question. I am a complete newbie to FCP 10 and have recently started a trial to determine which video editing product to use going forward. 

I have tried to search for an answer to, what I'm sure is, a very basic question but due to the keywords I'm searching for, I get a whole host of different answers back. I think that's the problem - I don't actually know what I'm searching for. I'm hoping someone here can help. 

All I want to do is to drag a basic title to later in my timeline but, if I move it more than a little, it drops down over the top of another clip. I have attached a video:

All I'm doing is having a rectangular box appear and then each bullet point moves into place as I talk. That's it. I just do not know why it keeps dropping down - anywhere aside from near the start of the title below it. 

Thanks so much for taking the time to read this and I apologise for I'm sure is a stupid beginner question. 

Did  you tried to make that title a secondary storyline before moving?

Hi - firstly, thanks so much for taking the time to respond. 

As it happens, within the last ten minutes I have managed to (sort of) resolve my issue. I basically started again with a new Project and this time I created each title from the tools menu. In my previous project I had copied a title (with the transitions, formatting etc) in order to save time. With the new project I didn't. Now I can move each layer completely independently and the issue doesn't happen. 

Right now I have no idea if copying the titles cause the issue but I thought I would explain in case anyone else sees this. 

I'm also going to go back and look at the potential solution you proposed. This is a very strange issue. 

I bet simply relaunching FCP and deleting prefs and renders would have fixed it, also. But what I'm seeing in that video should not happen in FCP no matter what.
