LGT-92 tracker data not stored on Cayenne

My LGT-92 tracker worked fine on TTN V2, but after changing the tracker and the gateway to V3 I can’t see stored data points on the map any more. The data arrives correctly and is shown in live data, but as soon as I click somewhere, the data is lost. Changing to map view a new data point is shown, but instantly lost when clicking on another widget. How can I make Cayenne store my data for at least the same day ? Tracker is V1.6

you can view the history in the Data tab.
