fan_speed and fan_speed_mode attribute disappearing

[mcv93us]

Hi, I just upgraded to the latest version of Home Assistant 2024.1.2 and after rebooting the EVA II PRO WiFi Midea Inventor Dehumidifier integration stopped working.
On HACS I saw the v1.04 update to resolve compatibility with HA, after the restart the integration was loaded without problems but I get the following error:

"Template variable warning: 'homeassistant.util.read_only_dict.ReadOnlyDict object' has no attribute 'fan_speed_mode' when rendering '{{ states.humidifier.midea_dehumidifier_12345678901234.attributes.fan_speed_mode }}".

In fact if I go to "Developer Tools = > States" I can see the following attributes:

min_humidity: 40
max_humidity: 85
available_modes:
   - Target_humidity
   - Continuous
   - Smart
   -Dryer
current_humidity: 68
humidity: 55
mode: Smart
device_class: dehumidifier
friendly_name: midea_dehumidifier_12345678901234
supported_features: 1

The "fan_speed" part is missing.
The interesting thing is that if I try to use the "midea_dehumidifier.set_fan_speed" service the speed changes and for a few seconds the "fan_speed_mode" and "fan_speed" attributes appear, then they disappear again.
At this point I don't know if it's a problem with the new version of HA or the latest integration update.
Can anyone else confirm the same problem for me?

Update:
I only now realized that the tank attribute is also missing: "tank_show".
