When attempting to import a translated XLIFF file, I receive an error message asking if I'd like to report the error, yet ~90% of the course is translated accurately. After retrying to import the XLIFF, no error message appears, and the remainder of the course is then translated. However, a portion of the slides show no text or images in slide/edit view. When previewed or published, the slide shows XLIFF mapping syntax (see screenshot). Any suggestions as to how this is happening and how to prevent it?
