Shelly smart home integration not discovering all devices

Hi, my Shelly integration is only discovering 3 out of 5 shelly devices. At the moment I have only installed in this setup 5 shelly dimmer2. Now, I’m only able to access 3 of them from HA.
I have checked that their MQTT settings of the 2 devices not discovered are right, so I don’t know what more to check or do in order to get them discovered. Any ideas?? Thanks.
