Cannot edit some parts of document

[saigais2339184351ky]

I am trying to edit a document in Indesign, and all was going well, but I've reach a part of the document that doesn't seem to be any different than the rest of the text, yet I cannot edit it or select anything in the section. I've tried several different things to unlock or edit, but to no avail. If anyone can assist with showing me how to "unlock" or edit the section, I'd appreciate it. The file is attached...

There are locked layers that you can unlock to edit.

Thanks for that! I unchecked lock on the layers, but I'm still stuck... Are you able to edit the specific sections "SAKE" and below on the 1st page, and "RED" and below on the 2nd page?

There is an empty text frame that is over top the lower section of page. You can delete or move this empty frame to access the multiple text frames at the bottom of page.
