Reporter field defaults to genderic 'admin' value when creating an issue

[lmadarang]

When one of my users creates any issue it defaults to a generic admin value, this causes a warning that it is not a valid value.  How do I remove this default value in the reporter field?  I do not want him to have to constantly manually undue this.

This is something probably configured in a post function on the create transition of that workflow. But it could also be another kind of automation. Check all the configuration that affect the field (postfunctions, listeners, automation plugins...)
