firebase - Parent document is being marked as "deleted" (italics) by default

Question

I am having a weird issue where our parent document is being marked as deleted. I am inserting a new document like this:

const userDoc = admin.firestore().doc(`/user_bundles/${context.params.userId}/bundles/${chargeRecord.course_id}/media/${chargeRecord.media_type}`);
return userDoc.set(bundleDoc.data(), { merge: true });

However, the "chargeRecord.course_id" document is being marked as deleted, resulting in empty queries.

I've ran into another question and answer where it explained this can happen when the sub collection is deleted. But to be clear we have not deleted this document. It was newly created for the user.
