The first one has the title changed by a metadata plugboard. The second one doesn't but the series info is being set by the driver the next time the device is connected. In this case, the driver is updating the database on the device to add the series info into the metadata the library shows.
My guess is that someone has changed the configuration. Since the first device was connected, the driver configuration was changed so that the series info is being set. And the plugboard has been removed. Or, if you have recently installed the KoboTouchExtended driver, a plugboard needs to be created for it.
