This was due to plugin clashes with Profile Builder. I resolved this by following below instructions:

Hi @jaymzwayne,
We’re aware of this issue and the fix for it will be added in our next update to Profile Builder. But until then you can manually fix it on your site, by doing the following:
Go to Dashboard -> Plugins -> Plugins File Editor -> now from the right side of the screen select the Profile Builder plugin and now from the “Plugin Files” section go to -> assets -> css -> style-back-end.css.
Now on line 1196, remove or comment out the following CSS style:
.ui-widget.ui-widget-content {
max-width: 95%;
}
Note: After you removed/commented this code, and go back to the UpdraftPlus settings, it is recommended to clear the browser cache (for example try CTRL+F5).
