The shortcode should be like this:

[catlist id=64,60].

For further information regarding the parameters of the shortcode, read the documentation provided by the author: https://wordpress.org/plugins/list-category-posts/other_notes/

I think the reason this is not working is because you're trying to combine two plugins that don't work well together. Probably the List Category Posts plugin doesn't have support for page categories.

You have two options now, explain what you're trying to do (I don't understand why you can use posts and categories) and maybe we can give you a better solution, or implement code which will return your pages from the categories you want.
