Error of losing value in payment module

[phongkni]

With the last update.
- The Amount, Cost values in the Payment module are all lost
- Create a new payment, unable to save the value entered in the amount and cost.
Please help me fix this problem and get back the values entered earlier
Thanks

I can't reproduce this neither in my local install nor in the online demo which I just updated.
Make sure you have backups as that looks like a mass edit or workflow that updated the values
Have you some workflow that may be causing that or have you made a mass edit somehow?
Can you reproduce in the online demo?
