Not recognizing some functions in external libraries as a function

Problem

I am writing this code:

import numpy as np

array = np.arange(100)
print(array)

When I am typing np.arange It shows me arange with a variable icon instead of a function icon. also, it doesn't show anything when typing parentheses. when I hover over it, it shows (import) arange: Any to me. But when I run the code it gives me the correct output and when I try print(np.arange) it shows me <built-in function arange>. This problem happens with some other functions in external libraries. For example, it also happens with np.array. It seems that pylance isn't recognizing these as a function.
