Pytest session scoped fixture is calculated several times - pytest

Question

I have following structure of tests:
tests
|__element
| |__test_create.py
| |__test_delete.py
| |__test_get.py
| |__test_recover.py
| |__test_update.py
|__conftest.py
I have fixture in conftest.py which must take the same value throughout the session:
#pytest.fixture(scope="session")
async def workspace_locales_set() -> list[str]:
random_locales_subset = random.sample(list(LOCALES_ALLOWED.keys()), random.randint(3, 7))
print("AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA", random_locales_subset)
return random_locales_subset
But all the tests, in test_update fall down because there comes a different locales value.
By the method of many prints, I found out that at the moment of switching from test_recover to test_update`, the fixture is calculated a second time
Here is tests report:

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA ['es-CL', 'kn', 'xog', 'es-PY', 'hi-IN', 'en-AS', 'en-TT']
As you can see, here is something weird: first the creation tests are run, then one deletion test, then the fixture is computed the first time, then the rest of the run tests go, and between the recovery tests and the deletion test the fixture is computed the second time
I use pytest-asyncio with asyncio_mode = auto. Could it have any effect?
But anyway, the session fixture should be calculated only once. What am I doing wrong?

Okay, that was really stupid. My PyCharm automatically added from conftest import workspace_locales_set in test_update file, so the fixture was called twice.
To fix it just delete all imports from conftest
