Currently, by default, if an Element with a mapping set up also has a default value, the default value will override any data from the Salesforce mapping. It's possible to change this setting so that if mapping data from Salesforce exists (non-empty Salesforce Fields), it will override any default value set for the Element. 

If you manually alter a field with either a default value or mapped value, the manually entered value will override that value.
