Hi,

I was under the impression that the non-filtered tag properties sent over MQTT Transmission would populate automatically in the MQTT Engine tags on BIRTH. So far, I tried many different scenarios with no luck to get this working.

**Versions:**  
Ignition Edge 8.1.33 - MQTT Transmission 4.0.20  
Ignition Standard 8.1.32 - MQTT Engine 4.0.20  
Default Sparkplug B namespace and other default settings

**Edge Transmitter Config:**  
Convert UDTs - **Enabled**  
Device level UDTs as Devices - **Enabled**

Under **Advanced Settings/Filtered Properties:**  
I have removed all the historical-related properties as well as the event scripts leaving only:

`accessRights;clampMode;deadband;deadbandMode;formatString;opcItemPath;opcServer;permissionModel;rawHigh;rawLow;scaleFactor;scaleMode;scaledHigh;scaledLow;tagGroup;valueSource;expression;expressionType;ConfiguredTagPath;readPermissions;writePermissions;parentEnabled;sourceTagPath`

**MQTT Engine → Advance Settings/ Filtered Properties:**  
Also removed the same properties so the MQTT engine autocreates the tags accordingly:

`accessRights;clampMode;deadband;deadbandMode;formatString;opcItemPath;opcServer;permissionModel;rawHigh;rawLow;scaleFactor;scaleMode;scaledHigh;scaledLow;tagGroup;valueSource;expression;expressionType;ConfiguredTagPath;readPermissions;writePermissions;parentEnabled;sourceTagPath`

When I subscribe to the DBIRTH topic I can see the properties are sent to the broker as expected:

On the Ignition tag browser only the **Read Only** property is properly updated on every tag under the corresponding Node/device of the MQTT Engine provider

What is the expected behaviour then?
