Thanks for the details. As I suggested this idea that I had after reading this thread may be just nonesense, but I thought it would be interesting to try.
This is recommended done with a copy of the project that you have now.
For now, let us assume that the missing track names are part of the locked Narration Track syndrome. I am not sure if your narration clip was generated in Premiere Elements narration feature or created elsewhere and brought into the program. That would be interesting information to have. But, nonetheless, moving forward with this idea.
Given you cannot move, delete, change, etc what is on this Narration Track. Whatever is on that Narration Track traces back to an original on the hard drive and probably is shown in Media Cache's (Adobe Folder) as conformed audio cfa and pek set.
a. Find the narration hard drive hard location and move it to a new location (special folder on hard drive). When you go back to the copy of the problem project, you should be greeted with one of those "Where is....?" messages. Cancel out of that. Do not do anything within that message dialog.
b. Right click the thumbnail for your narration in Project Media and select Replace Footage. Then browse to and select the original that you had moved to the computer desktop and the special folder there.. Click OK. That should restore the file (including whatever effects were made to the file) to the project.
c. Has any of that had any effect on unlocking the Narration Track?
Other maneuvers to try
a. Trying to locate and delete any cfa or pek files associated with the problem audio.
b. Switching to an Aero Theme for Windows if you do not have one set so far.
Thanks for giving all of that a look at.
