When hitting the replay button on the asset charts page, all (fixed value) flex-config fields disappear. They reappear when the replay is stopped. I haven't tested whether the same happens for (sensor reference) flex-config fields.
The solution is probably to set the belief time of this data to the start of the selected date range, so that they show up whatever the replay time (as a priori beliefs).
