Export deleting columns

Version: 6.2.7
Build: 6265

Issue:
When creating a filter and adding columns, upon exporting to jira (current fields only) the export does not contain 1 or more of the columns that are on display in the filter.

Steps to reproduce:
1. Open up any filter
2. Add "Story Points" column
3. Export to excel (current fields only)
4. Open up excel
5. All columns are there except Story Points

Expected behavior:
1. Story points column to show up in export

Additional Information:
I am viewing filter in list view
When trying to sort story points column, the column disappears entirely
Saved filter multiple times after adding story points
