Netgear R7000 Realtime bandwidth stats won't save

Hi There, I'm running Tomato Firmware 1.28.0000 -2.5-124 K26ARM USB AIO-64K on a newly purchased Netgear R7000.

Bandwidth stats only work in RealTime
but they won't save, for subsequent display of daily, weekly, monthly graphing.

However, the IP Traffic Stats work fine in realtime and save...

Is there a known issues with bandwidth stats not saving?


I'm currently writing both sets of stats to CIFS1, which is located on a windows server file share.
