Well, it depends on which title template you're talking about.
You can certainly add and remove individual elements for any title. The new Motion Titles in version 14 are particularly customizable.
Premiere Elements 14 on Windows 10 64 bit.
When you create your text title in the project's opened Titler, your colored text is on a black background. That black is not the color back but it is the way that the project represents transparency. Consequently, when you place the text title on Video 2 above the video on Video 1, the video from Video 1 will show through (your text overlay effect).
If you want to create a text title slide with a colored background, consider...
1. Go to Expert workspace Project Assets Panel Assets New Item and select Color Matte to create a color matte having your choice of color.
2. Then place the Color Matte on Video 1 below the text file on Video Track 2.
Have you been there and done that?

I'm using the default page, as it seems a likely candidate for color change. Nothing fancy, just want to pick the color of the background and then the color of the font.
That was so successful, I can hardly contain myself! Thank you!
Great news of your success. Great job.
I admire your enthusiasm in your projects.
