Tasmota switch entities have disappeared from default dashboard

Hi, moved to HA a couple of months ago from OpenHAB. I have about 20 sonoff devices, a mix of basic Mini, dual and POW. They are all flashed with with a mix of tasmota 13.4 or 14.0. I’m using the Tasmota integration, but have MQTT configured.
All the devices and entities were in the default dashboard. The other morning I noticed all the switch entities had disappeared from the dashboard.
I have no idea why or how, has anyone else experienced anything like this.
