Odd Park issue

We installed a Freepbx system version 2.10 Asterisk 1.8 We have installed AAstra 6731i phones. The customers system had 3 calls parked. All three calls were showing on BLF keys on the 6731i phones. A user picked up the 2nd parked call on 72. For some reason she was looking at the phone and watched the BLF key for the call parked on 73, move to the key she had just picked up. I have never seen this myself, could there be something going on?

Thanks for any insight

Anyone have any ideas???
