Unable to see new entities after changing from ZHA to Zigbee2MQTT

[lynchpinhags]

Hi all,
I started using Fusion a little while ago and and got a few basic things running in this very slick looking dash. Today I switched from using ZHA to Zigbee2MQTT, and after doing so, my door lock (Zigbee) was listed as unavailable in Fusion. When I try to edit the button so that I can pick the new entity for the door lock that was added to ZigbeeMQTT (and works just fine in the rest of HASS), I find that it's not visible. Only the old ZHA entries are there, which are now unavailable since I no longer use ZHA.

Is there a way to refresh the entities that Fusion has access to?

Many thanks!
