How does the Export project work in the latest version?

I apologize. I found the source of the problem, was project CMS October, I deleted and now the folders and files are fine.

What has changed in the update? Before, files and folders looked like this and now, as in Figure 2.
The settings are mapped to html, now the files are in htm format?

Nothing has changed in this update for exports. Have you set the CMS to none?

CMS was but now none and everything works fine again.
