Most likely the adhesive has given up. We've had a couple pieces of seam tape come loose on the Cougar.
Looks like the tape is still in good condition except that it is lifting from the surface. If you can pull it back without tearing it, clean the surface with rubbing alcohol and reglue it with contact cement. I used a piece of masking tape to hold the seam tape in place while the glue dried and haven't had to do the same spot twice...yet
