Issue with IDE's hints behaviour with arguments

[rouol]

I'm trying to wrap my C++ math library to the Python module, but experience strange issues with python argument docs.

For example, I have a C++ function:

std::pair<std::vector<Eigen::Vector2ld>, std::vector<Eigen::Vector3ld>> GetPoincareMap(
	PlaneEquation planeEquation,
	std::vector<Eigen::VectorXld> trajectory)
	{...}

and binding for it:

module_handle.def("GetPoincareMap", &DynS::GetPoincareMap, "Returns Poincare map from input trajectory", py::arg("planeEquation"), py::arg("trajectory"));

docs from help look fine:

GetPoincareMap(planeEquation: Tuple[float, float, float, float], trajectory: List[numpy.ndarray[numpy.longdouble[m, 1]]]) -> Tuple[List[numpy.ndarray[numpy.longdouble[2, 1]]], List[numpy.ndarray[numpy.longdouble[3, 1]]]]
Returns Poincare map from input trajectory

but in PyCharm for example, resulting hints are weird:

I am using Python 3.9. Checked on a few Windows 10 machines with CMake build and setuptools with MSVC compiler, in WSL Ubuntu using CMake and built-in g++ and in macOS 10.13 using CMake and g++-11.
Actual source code for CMake here: https://github.com/FishermenOnTuesdays/DynamicSystem and here for setuptools build https://github.com/FishermenOnTuesdays/pydyns

Are there any solutions to this issue?
