Github: PGP key usage flags do not allow signing

Question

I used my OpenPGP key to sign a git commit, but it displays as "Not verified" on github: https://github.com/cweiske/jsonmapper/commits/master

Use flags for a signed key do not allow signing.

GPG Key ID: 14C85A0824EAF823

gigub gpg signature docs do not report this error.

So my questions are:

• How can I read these flags?
• How can I change my key to allow code signing?
