Assuming Premiere Elements 11 through 14 on Windows 7, 8, 8.1, or 10 64 bit...
Do not use Copy/Paste unless you want to use the same titles in all the various places of the project.
In Expert workspace, create your title in the opened Titler, and close the Titler when finished. In the creation process, a copy of the title will be placed on the Timeline at the position of the Timeline marker. Also a copy of the file will be placed in Project Assets.
With the Titler closed, open Project Assets, right click the thumbnail of the copy there, select Duplicate. Drag the Duplicate to the Timeline and double click it to open the Titler to edit it there. Repeat the process for additional titles as indicated by your workflow plan.
Please review the above and let us know if it targets your question. If not, please detail what supplemental information you need.
Add On...you do not want title thumbnail in Project Assets with the same file name.
Thank you again! For anyone else seeing this I am using PE13.
Thanks for the follow up. Glad the suggestion worked for you. Great job of follow through.
If you are working with 13, have you updated it to 13.1 yet using an opened project's Help Menu/Updates?
If not, the following will describe the perks of the 13.1 Update
Are you using Windows 7, 8, 8.1, or 10 64 bit or Mac?
Best wishes moving forward with your Premiere Elements workflows.
