Metadata letter case issue

[andr11b]

Admin plugin saves all similar metadata that wrote in different way: 'description' and 'Description' both will be added like two different metadata.

Can you give me an example of what you mean? How are you entering description both ways? via the frontmatter, or via the forms?

[andr11b]

I talk about case sensitive of added metadata names (and no matters how i add it - via the frontmatter, or via the forms ):
Frontmatter:

metadata:
    Description: test
    description: 'test'

Output html:

<meta name="description" content="test" />
<meta name="Description" content="test" />

And when i use something like page.header.metadata.description in the twig-templates it is different of page.header.metadata.Description.

P.S.:Sorry if my poor English is hard to understand.

I think we should force to lowercase.

Fixed in Grav develop branch (not an admin issue)
