Unity Bug Reporter does not display all attached files until the report is previewed

In the bug reporter, it doesn't display all the attached files (logs) when trying to submit an issue. Users would have to preview it to see the actual report and files. If these files can still be seen in the Preview form, why can't they be made visible in the submit form but have them greyed out as they can't be removed from submission?

STR:
1. Create an empty project
2. Select Help > Report a Bug...
3. Check the Attached field
4. Fill any fields if necessary and click Preview

Current Result: Files attached between Reporting and Preview is different (see attached screenshot)
Expected Result: All files that are attached on the report should be shown under Attach field and scrollable (if necessary)
