Hello, this is because I mapped the crossing separately from the traffic_signals, so I followed the instructions on https://wiki.openstreetmap.org/wiki/Tag:highway%3Dtraffic_signals under "Vehicle traffic signals before intersection, pedestrian crossings separately mapped ":
- Road traffic signal: highway=traffic_signals + crossing=no + traffic_signals:direction=forward/backward (https://www.openstreetmap.org/node/10831776497)
- Crossing traffic signal: highway=crossing + crossing=traffic_signals (https://www.openstreetmap.org/way/684272619)
- Crossing footway: highway=footway + footway=crossing (https://www.openstreetmap.org/way/684272619)

There maybe are mistakes though, but I believe I did it correctly for the aforementioned elements. Maybe I did it wrong for others though.
