that's weird... usually, after saving your changes, the moving back to the profile page (not staying on the edit page), then forcing a page refresh (usually F5) will show your recent edits, though typically even the refresh is unnecessary. There's usually a message that appears after saving about that, but the message can be misleading, because force refreshing while still on the edit page will save the page again (and it doesn't appear that you're doing that).
a typical reason for edits not displaying, are missing or incomplete <ref> tags, but I didn't see any of those problems with your edits.
but primarily, you should also be able to verify your edits by looking at the changes tab and seeing your recent edits listed there. Once listed, you can view the differences between versions to verify your edits. If they are not getting listed here, then somehow your changes aren't getting saved when you click the save changes button. But if that were the case, you should get a warning message about losing changes when moving away from the edit page.
otherwise, I'm at a bit of a loss to find a reasonable explanation for what you are experiencing.
