Why is my title clip is overlayed by clips below it
I have a title at the very top of my timeline.
Quite a bit of stuff underneath, including a compound clip.
But I can't understand how this title selected in the screenshot below, can be "partially showing" - admittedly it's a foreign character so it might be hard for you to tell, but you can see the actual words at the top of the purple clip - only half of it is showing in the viewer. You can see the selection is wider than the text showing, at least.
Now, I sort of know what's going on, it seems to be allowing clips (photos) in the compound clip, at the bottom, to "overlay" on top of it.
But I don't understand how this is even possible. Shouldn't a title clip at the top, trump all?
If not, what do I need to do, to get this title overlaying everything?
