Step count decreasing throughout the day

This morning step data using fd(steps) was consistent with Google Fit step count. Throughout the day the count has been drastically decreasing in KLWP, yet is still accurate in Google Fit.

I have never encountered this before today, which happens to be when DST has ended, so possibly this may have something to do with this issue?

Was that day the one when DST changed?

Yes. Also yesterday's step count is off using r1d,r1d. If I use r24h, r23h instead it is correct.
