status not changing in Charm

Hi ,

we are facing an issue with Request for change , when we release it for development the status doesn't change , it takes the previous status which is for Example "Approved" ,

These are the Status we have got :

1.Created

2. validation

3.to be Approved

4.Approved

5.Release for Development --> the status is not changing still "Approved"

there are 2 warning messages:

1.status was reset by the system

2.change documents can't be generated.

Please help me to find the error !!

Thanks
