Chapter formatting reverts

Several times I have applied a format to all my chapters (top level folders) in the Editor, and after closing/reopening the project, formatting reverts to what it was. I’m not sure when that started, but it’s rampant now.

What’s going on?

Just to be clear, I’m setting chapter formats using a process described at the Evernote link below. It appears to work perfectly, but when I close and reopen the project, formats revert to what they were.
