To what Premiere Elements 12 title template (lower 3rd type) are you referring?
It is not clear what you want to do.
a. Are you able to double click the template to open it in the program's Titler?
b. Can you select the present text with the Selection Tool to move it to custom locations?
c. Can you edit the existing text in the template?
The following uses the Aquarium lower 3rd template...where do you want to write text in the template?
We will be looking forward to your follow up.
