Strange Groups Behaviour

I have a “Windows” group binary_sensor.windows, and a doors group binary_sensor.doors, that include all of the zigbee sensors on my windows and doors, respectively in my installation.

I have an automation set to sound a chime whenever a window or door is opened.

Today, I opened my kitchen window and noticed that the chime did not sound.

I checked and found that the sensor was not reporting the correct open/close to HASS. I replaced the battery and it’s now reporting correctly, but still not sounding the chime.

I tried to check the configuration of my sensor group under helpers. The group is there, but when I click on “Group options” to check the configuration, nothing happens.

I have restarted HASS but nothing has changed.

How do I check/edit the members of a group?

Has something changed in a recent update?
