If there's a title card that is NOT to be superimposed it can be placed on track one. Or a higher track. Keep in mind that higher tracks take precedence, so if the title card is full screen on track 2, then nothing will show from track one. If the card is scaled down, then track one will display 'behind' the title. That's a picture-in-picture effect.
If the title has a transparent background, such as titles created with the Videopad tool, place is on a higher track, immediately above the the background content.
The VPJ is a control file that tells the program what to do. It's not meant to be displayed. When a project is saved or saved AS, with a unique name or # - so as to not overwrite earlier saves - it creates the VPJ. When a VPJ is double-clicked it opens the saved project associated with it.
If you get a "resolve' prompt, then the source file used for that project has either been removed or deleted. Don't do that until the project is complete and will never again need to be edited. Click the RESOLVE button and locate the file on the PC.
Then save AS the project so it updates the VPJ to the new file location, while leaving the earlier VPJ file as is for protection.
Save Project file AS is available from the Home toolbar - click the caret to the right of the Save button. 
There should be no problem adding clips to the head of the project without disturbing the existing content, which will shift to the right. No track two is created.
Right-click the clip in the bin (top-left) and Place on Sequence at Start. Works just like this...

VP is pretty friendly, but it's more full featured than WMM. As with all software, there's a learning curve. Click the ? at the top-right for HELP. And at the top of this forum, choose the link to the tutorials.
