[bug?] zigbee2mqtt link disappears after save

Hello,
when you click on Save on a Z2M device after updating a room for example, the link to zigbee2mqtt disappears until the next page refresh.
Is this intended behavior?

It’s not intentional. I’ll look as soon as I can.

Here’s a correction

I take this opportunity to ask a small question: I have had to stop and restart my server several times recently due to work.
Each time I have to restore a backup of the Gladys configuration and each time, the services start but the link between MQTT and ZIGBEE2MQTT does not happen. As a result, my sensors no longer report anything and I have to reset the integration and add the sensors again.

Do you have any leads to solve this kind of thing?
