Zigbee devices - 'MQTT sensor' in Devices and Dashboard - unable to control

I have: PI4, with following:
Home Assistant 2023.2.5
Supervisor 2023.08.3
Operating System 9.5
Frontend 20230202.0 - latest

Also two add-ons: Mosquitto broker, version: 6.3.1;
Zigbee2MQTT, version: 1.33.0-1

Zigbee devices are registered with Z2M and are shown at Z2M dashboard with their properties

However, when I go to Devices, only 1-2 of these devices show their properties, others show as ‘MQTT sensor’ without the ability to control, like toggle turn/off switch

Here, in dashboard, all switches/energy monitors show as grayed out

How do I fix this? When I click on switch’s dashboard settings, there is a message

This entity is no longer being provided by the mqtt integration. If the entity is no longer in use, delete it in settings.

Also if I go to Entities, all these switches have exclamation mark in the status column.

Help please
