BICEP - Parameter file variable assignment - azure

Question

I was following the repo for separate parameter file to each env as defined in the https://github.com/Azure/bicep/discussions/4586
I tried the separate parameters file for dev, stage, prod but the value assignment in main module variable remains flagged by intelligence even though it exists same param exist in the respective parameter file.
Other approach I tried is loadjson variable, but it does not show auto completion for items under subnet block as it stopes right after value.
Maybe I am overthinking and not applying the correct approach, Perhaps I should ignore intellisense and try deploying by applying parameter and hope it will auto pick correct value during the deployment param check.
Here is my parameter file and the same value applies to each env param json.

You appear to be attempting to deploy an Azure Resource Management (ARM) template using a parameter file.
The parameter file is used to pass values to the ARM template during deployment. The parameter file must use the same types as the ARM template and can only include values for the ARM template's parameters.
You will receive an error if the parameter file contains extra parameters that do not match the ARM template's parameters.
In the same deployment process, you can use both inline parameters and a local parameter file. If you specify a parameter's value in both the local parameter file and inline, the inline value takes priority.
Refer to create a parameter file of an ARM template
About the different parameters file for dev, stage, and prod, it's likely that the parameter file is not correctly linked to the ARM template.
You can deploy the ARM template with the parameter file to determine if it will automatically select the proper value during the deployment parameter check.
Regarding the loadjson variable, it is possible that the loadjson variable is not properly formatted.
You can double-check the loadjson variable's format to ensure it's proper.
After a workaround on this, I created a sample parameter.json file for a webapp to deploy in a production environment and that worked for me.
Note: Alternatively, You can use az deployment group create with a parameters file and deploy into Azure to avoid these conflicts.
