Magitek Sawback animation not working?

This might not be a bug, but I thought I should post it here just in case, as I'm a big GMB fan. The two magitek Sawback weapons for the GNB (Both Chondrite and the Imperial Magitek one from tower of babel), dont seem to have animations like all the other melee weapons from that group.

The chain teeth seem to be seperate from the main weapon model, so I dont know if it was never intended to be animated, or it was and something is preventing it from doing so.
