Yes, that is a calibration issue. The BMS is not sure where the true low and high is. Could be based on how it was consistently charged before. Nothing to worry about. I'm at 276 at 100%.
Great thread here:
How I Recovered Half of my Battery's Lost Capacity
I'd suggest setting your charging scheduled departure time. Why? Because then you sit at your starting SOC for some more random amount of times and snapshots can be taken for the auto-calibration BMS work. See above thread.
