Default [Q] Restoring text messages from backup on 4.4?

I just rooted my phone to install the Google edition ROM but before I did I backed up my texts using Wondershare MobileGo. I've used this program to backup and restore messages, contacts, photos, etc. on my phone many times before and on previous phones and it has worked fine. But this time when I try to restore my messages they don't show up on my phone. To be specific, when I first do the restore the threads will show up under the contact name but there will be no messages when I open the thread. Soon after they just all disappear (only the restored messages, not any new ones). It seems like they're getting deleted as they're empty threads but that's just a guess. I thought it might have been a problem when doing the backup so I opened up the file (.sms file) in notepad and all the messages are there. I think it has something to do with Kit Kat but I've never encountered this problem before.

So does anyone know how I could restore my messages from the .sms file I was given from the backup or why the messages don't show up on my phone? Thanks!
