What version of Premiere Elements and on what computer operating system is it running?
Generalizing for now....
Create your text title in the Titler. Close the Titler.
Go to the project media area, find the copy of the text title there. Right click that thumbnail, select Duplicate.
Then drag that Duplicate to the Timeline.
To open the Duplicate in the Titler for further edits of it, double click it.
Please review and consider the above, and supply more details. Any questions, please do not hesitate to ask.
