empty msg box after update library

[ease-zh]

When I click the "Update Library", it always returns an empty msg box as:

[GYC-lab]

I guess there are several mismatching .md files. You may need to check your .md files generated from .json file, and delete some accidentally generated .md files, which works for me. Maybe re-generate the .json file is also a choice.

Hope it works for you!
