Free@Home channel misses 2.0 devices

App version: 2.27.2
Phone OS: 14.4
Problem description:
Free@Home Busch Jäger channel misses a type of device: The 2.0 Sensor (2 sensor channels, no actor channel) - This is used e.g. to activate 4 Buttons for Scenes triggering etc. This device is configured in our network, but even with removing the channel and re-adding in Olisto (Which seems to always be required so it picks up new devices, which might be a bug as well), it does not show the 2.0 Switch type.
