Chargers disappear when zooming in

Since a few weeks (?), ABRP shows no chargers any more when zooming. The example screenshot shows “Ladestation finden” with a filter 150 kW +.

When I start zoomed out quite far, all interesting chargers are shown.

If I zoom in very slowly step by step and wait for the list refresh every time, it works as expected.

But if I zoom in “normally” which means more than one mousewheel-step, all (!) chargers suddenly disappear.
