Since https://jira.mongodb.org/browse/COMPASS-4332 was closed as fixed and not re-opened when users reported that the issue wasn't fixed, and since I encountered the issue with the latest stable release, I'm reporting a new issue.

Problem Statement/Rationale

There are two issues: First, when exporting a collection, not all the fields in the collection are present in the selection dialog.

It would be nice if the selection dialog included fields at least from the first and last documents of the collection if not a sample of the whole collection.

Second, and more importantly, even if one explicitly adds the missing fields to the export, they're not included in the export.

~ $ head -n 2 ~/Desktop/statuses.csv
_id,bps,ch,lock,pps,seq,snq,ss
60f9e3b8970d2eea35726954,0,auto:34,atsc3,0,0,100,100

Steps to Reproduce

Create two documents in a collection, {'a': 1} and {'b': 2}. Attempt to export the collection to CSV and have `b` appear in the output. Can't be done.

Expected Results

What do you expect to happen?

It should be trivial to export the full collection to CSV.

Actual Results

What do you observe is happening?

Fields are missing from the export.

Additional Notes

Any additional information that may be useful to include.
