Hi Tim! Thanks for the prompt response. We actually upgraded from 1.9.5 to 2.2.3 and it's the first time we've experience this. I went to check how the questions behave thru Admin - Plugins-Questions behaviour-Manage question behaviour-manual grade. It shows that Manual grade is enabled.
Please advise when this will be resolved and what steps we need to take moving forward.
Thanks in advance for all your help.
Maria
