Unable to edit text on template layer doesn't exist

[Gabrielle]

I licensed a "full editable" template. I started editing text layers until it appeared I could not edit the main headline. I clicked through all the layers in the text folder turining visible and invisible, to make sure that I didn't miss it. It never went invisible. Then, I turned the text layer folder invisible and the headline went invisible. I feel crazy. How do I find the layer to edit??

File in question is: 139281833

Thanks for your help!
