I am trying to compile a python function written in python 3.6 in a simulink function block using coder extrinsic. However, I have been having two very wierd issues:

In many cases, the matlab gives an error that function "py.A1.test1" is undefined for the type double, which they are not and are in the same folder as the simulink model.
When I can get it to work on very simple python functions like adding inputs, when I try to change the python function (while keeping the same names for python files and function) and re-run the simulation that calls the python function, it uses the old (previous version) of the python function rather than the updated one.

Are these two bugs in the model or I am missing something as I receive similar errors in 2019 and 2020a versions. The exact error messages are as following:

Undefined function 'py.A1.test2' for input arguments of type 'double'. Error in 'abdaasdasd/MATLAB Function' (line 4) out = py.A1.test2(in1,in2);

Component:Simulink | Category:Model error

An error occurred while running the simulation and the simulation was terminated
