"Default Sort Field" keeps changing to "Thread title"

Does anybody know any scenarios where something would keep altering this. This is the third time its happened now and ive had to run some SQL query's I found to globally set them back to newest first/descending etc.

I know it could be a mod that ive installed but also that it could be something else im not sure, Does anybody have any idea what kind of problem or mod can cause this to happen and is tehre a way of stopping it from happening in future?

Thnx, Help appreciated.
