Unresolved references when specifying 2 sources root

I am trying to mark two directories as Sources Root in my project for autocompletion functionality:

• src/opentelemetry-python/opentelemetry-api/src
• src/opentelemetry-python/exporter/opentelemetry-exporter-zipkin/src

If I mark both directories as Sources Root, autocomplete only works for opentelemetry-api while the zipkin modules are unresolved.

If I mark only one of the directories as Sources Root, autocomplete works fine for that directory. For example with zipkin:

Interestingly, if I change the top-level module name for the zipkin source directory, it solves the issue, so it would seem that there is some type of conflict / overwrite occurring within the autocomplete functionality:

Here is my interpreter info:

Troubleshooting I've already tried:

• Invalidate Cache / Restart - no effect
• Delete & recreate python interpreter - no effect
• Add src paths to the Python Interpreter instead of using the Sources Root GUI functionality - same issue
