Cardio load suddenly very low

[Nicolecg]

I've been using my sense 2 for a couple of years and mostly met or exceeded my daily target. Suddenly I cant get anywhere near it and I'm wondering if its a problem with my fitbit recording the activities. I don't do huge amounts of exercise but I walk my dog every day, yesterday I walked her for about 40 minutes in tbe morning and an hour at lunch and I had a cardio load of 7 for the first walk and 1 for the second. I reached my target steps of 12500, I was on my feet most of the day doing various things and yet my overall score for the day was 29. Even on days where I add in cardio or pilates, I very rarely go above 40 whereas I used to be above 80 regularly for the same activities. Any suggestions?
