Hey,
Qualtrics has a few quirks regarding how it saves data from questions and Embedded Variables under-the-hood, and this might be a long shot, but you could try to retroactively change the question type, and re-download the data.
I've had data from Embedded Variables magically appear by creating them retroactively, so this might work.
Of course, retroactively modifying a survey after data collection is generally a very bad idea so Qualtrics might warn you about potential data loss. Make sure you have a safe copy of both the survey and the collected data before you make any changes.
