1. Enter a directory with around 10 files in Multi-column view.
2. Right click on the first file, select Rename.
3. Modify the filename.
4. Press <Enter> to confirm the modified filename.
5. Press down Cursor, to move to the next file in the list to rename.
6. Observe that the down Cursor skipped the next filename, press the up cursor and observe that it skips over one in the upwards direction as well.
7. Sometimes it does not happen until the 4th or 5th file etc, so repeat steps 3-5 using the keyboard until you see it.

Kind regards
