Error change central password


I've updated Password Manager to version 5.8. When I change a user's password, everything works fine, but when I choose "Forgot my password" option and I answer the questions, two events are generated by the captureAgent installed in the AD. So two events to change central password are triggered. I receive this error email:

PwdErrors Updating the user account: xxx xxx, xxx

xxx xxx, xxx was changed by another user.

Updating the user account: xxx xxx, xxx (xxx xxx, xxx)

xxx xxx, xxx (xxx) was changed by another user.

The password is not propagated to LDAP. Could this be a bug of the version or is it possible that I have something bad configured?
