Doc Import: Empty page title message will reset all advanced settings

• Import a word document.
• On the configuration screen, change the settings, and set an empty title
• Click Import button

There is an error message: "You must enter a title."

All of the settings are reset to the default.

This is annoying, as the user has to change the title, and also redo all of the configuration. They also may not notice that the settings have been changed, and save after only correcting the title.

Instead, the settings should remain set if the user tries to save with an invalid title.
