Anyone else having any distance inaccuracies or is it just me?

So I did two walks today: one outside for 5mins and one on my walking pad at 3.0 mph for 15 mins. The distance for the 5min walk is 0.17mi and the 15min was 0.13mi. How is that possible? I checking the units of measure on both the watch and the Samsung Health app and they are both in miles. Earlier this week I checked for updates on my watch and reset it due to troubleshooting with Samsung about my sleep being recorded in accurately. That is fixed, but now the distance in off.
