As above. I get a success message when I update via plugin page or updates tab. It is also set to auto update and I get a success email. However whenever I reload or visit the plugin page or updates page it's back to version 2.1.14 and it says it needs updating.
Actually, it is the new version 2.1.16 but the version in the file mb-settings-page.php is still 2.1.14 and causes the issue. I've escalated it to the development team to release a quick fix for this.
