Symptoms:

In AfterShot, image metadata cannot be edited, even if fields such as Subject, or Creator are added to the Metadata viewer.

Cause:

AfterShot (as opposed to AfterShot Pro) is not able to edit metadata.

Resolution:

If editing image metadata is essential to one's workflow, Corel recommends upgrading to AfterShot Pro. Click in the lower left corner of AfterShot to upgrade to AfterShot Pro.
