In addition to the steps, please ensure you performed these on your new project:
- add the NexJ Finance as a mixin
- add the Data Solutions DataImport as a mixin with override checked
-  Model Version should equal dm:import:Main.Version
On the project Module name should equal the module name on DataImport, which is “dm:import”
In regards to the aspect you may have to add the fields covered by the aspect to your new table.
Also having “XExtId” implies you are extending the core table Account, if I am correct then the aspect DM_DATALOAD is not required for core tables, it used on staging tables.
