Issue while creating Incident Maintenance Notification -EHS

Hi Experts,

I have an issue/error which is when creating maintenance notification via task .Actually while creating notification the only mandatory field is 'Title' as per the symbol beside the field.Once i filled the fields its givening error message 'Mandatory field "Notification Type" must be filled' this is not a mandatory field.

Below are the screenshot of the same.

Thanks in Advance.

Bob.
