Activity minutes off when running using HRM600

Since a few weeks I've beenr unning with the new Forerunner 970 in combination with a HRM600. All worked fine, but since 2 weeks I experience weird behaviour when running with this combination, regarding the activity minutes.

During the first weeks my activity minutes where ok. But in the last 2 weeks doing an easy run in zone1, Connect "gives" me activity minutes like I'm running in zone 2 (light/licht) and 3 (vigorous/intensief). See blow screenshots:

This only seems to occur when I use my 970 together with the HRM600.

However. When I run with only my 970, the activity minute look like they are OK. See screenshots below:

Anyone else experiencing this issue?

Regards Frank
