Default [Q] Not able to delete message threads in my I8552

Hello developers and Non-developers too like me

I have rooted my device and installed DocDroid Extreme in it but I didn't like it much so I again installed the Official ROM. After that I restored my data from SanDisk Memory Backup App which I backed up before rooting my device.

The problem I am facing is that m not able to delete the message threads in my phone. Whenever I delete a thread the message is deleted but thrread is still there with the contact name and without any message in it.

I have attached an image of that.

Please help me out guys.
