Inconsistent poetry detection

[pdc1]

Hello,

I have three poetry projects, and two of them get detected and one does not. For the one that does not, the poetry environment gets detected as a venv environment instead. That generally seems to work, but I am nervous that it is not correctly identifying poetry, plus then poetry is not set as the package manager.

If I force it by adding this to my project config, then I get an error about an invalid python interpreter being selected.

    "python-envs.defaultEnvManager": "ms-python.python:poetry",
    "python-envs.defaultPackageManager": "ms-python.python:poetry",

All three poetry environments are in the default "global" location, ~/.cache/pypoetry/virtualenvs/

Are there some steps I can take to see what is going on?

I looked in the output of Python Environments for the project. In particular this part looked promising, but it ends up identified as venv and not poetry:
