JabRef development version, Arch Linux.

• I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists

Under entry table column in preferences I am not able to change the order of the columns by more than one column, on saving the order and reopening the Bib file the changes aren't reflected.

Edit: Apart from the column order the column names aren't updated either.
