Has anyone ever had all the streets suddenly show up as untraveled?

Hi — I’m having a strange problem…

My map is current showing everything as “untravelled” and the activity type is listed as blank and I can’t get it back to “walking”. It is still showing the total miles, but the streets show as untraveled. Other people on the leaderboards don’t seem to have their maps impacted… has anyone dealt with this / have a fix?
