Update Enabled Checkbox Grey Out

Summary:

Try to use VBCS to import external purchase price. We are able to import external purchase price. But when we try to update by download the data, we find update enabled checkbox is greyed out in advance tab. We are not able to make any change for download data. I would like to know how can we enable it again.
