Issue Summary

Creating a Date Picker custom field with the name: Start Date (similar name to the locked Start date system field) results in problematic behavior when trying to add the custom field as a column to the List View of then filter as the newly created custom field doesn't show up as a selectable option.

Steps to Reproduce

1. Create a Date Picker custom field and name it Start Date (notice both capital letters).
2. Edit an existing filter or create a new filter and click on the Configure Columns option for the List View of the filter.
3. Try to search for the newly created Start Date (notice both capital letters) custom field and notice that only the locked system Start date field shows up.

Expected Results

Both the newly created Date Picker custom field Start Date and the locked system field Start date show up to be added as a value for a column under the Filter's List View

Actual Results

Only the locked system field Start date value shows up.

Workaround

Rename the Date picker custom field to something unique (e.g. New Starting Date) for it to show up in the results.
