When importing new data, it is possible to overwrite the meta data in the project with the meta data in the imported file. This allows automatic processing of updated question and answer labels in the cases where the correct labels always are defined in the data source (for example the data collection system or any other internal databases). 

It is not recommended to use the option in projects where the labels are being edited in Dapresy Pro as these edits will be lost when new Meta data is imported as these are replaced with the labels in the latest imported file.
