Shared GPS Time returns internal system time on 3DM-GQ7

[scotts11]

I am using the 3DM-GQ7, and I am trying to include the Shared GPS Time (message 0xFF 0xD3) in both the AHRS_IMU data stream and the ESTFILTER data stream). I am getting GPS Time correctly from the GNSS1 channel (only using one channel right now), but the AHRS_IMU and ESTFILTER data streams are just returning the internal system time (basically seconds since the system was powered on).

One of the channels (ESTFILTER) has the valid bit set for the GPS Shared Time, and the AHRS_IMU channel does not have the valid bit set for GPS Time. The GNSS1 channel has the valid bit set, and the time looks correct.

Do I need to initial the Shared GPS time?
