Quick Documentation Issue with Pandas, Numpy in Python 3.7

Hi, 

I am having issues with Pycharm quick documentation. When I try to visualize quick documentation in an environment that has Python 3.7, Numpy, Pandas do not show information in the quick documentation. When i try to get documentation for array, get "numpy. core.multyarray _all_:Any = [..." message as you can see in the next picture:

This happens with almost all the numpy functions. When I want to see documentation for sqrt it happens something similar: ""numpy. core.umath_all_:Any = [...""

Something curious is that if I change the environment to a python 3.6 the quick tool work perfect. as you can see in the next picture: 

Does any body know how to fix this issue? 

I am running with Anaconda:

Pycharm:

If somebody can point me in the right direction to fix this issue. 

Thanks in Advance
