Problem:
I expected to see:

The Chinese flag provided by wpml at
https://cms.apptweak.com/app/plugins/sitepress-multilingual-cms/res/flags/zh.png

Instead, I got:
a broken image, pointing to : https://cms.apptweak.com/app/plugins/sitepress-multilingual-cms/res/flags/

Solution:
The language code will be used to locate the flag.

since the language code is zh-cn and there is no zh-cn.png flag it will be displayed as broken.

Go to /plugins/sitepress-multilingual-cms/res and in there you can duplicate the flag for zh.png and name it zh-cn.png or even rename it.

However, I'd recommend downloading it to your computer and uploading it through
WPML->Languages->edit languages -> custom flag.

This will ensure the flag remains even after plugin updates.
