Item Auto Status, & etc

I just discovered that by giving weapons special properties (cmd: Jump, X-Magic. Other properties like MP to 1, Vigor 50%, HP+25%, & etc too), and then during the battle, we go to the item cmd & change the wpn to something else, the cmd (& maybe other special properties) that was given by the previous wpn still remain throughout the battle. Is there a patch that fix this?

[The Vigor+50% seem to work properly though, as removing it during battle does lower my physical dmg.]
