Cannot revoke my Stellar address proof

I had one of my Stellar addresses compromised. To avoid anyone to send any further funds to this account I have created a new wallet inside KeyBase, set it as default and deleted the compromised one. All works fine despite one thing. When I open my profile, on "Chain" tab (https://keybase.io//sigchain) I can see two of those addresses proved as mine. Tried to revoke the proof of the first address, but it is not possible (tried from either from KeyBase GUI or CLI). There is an option to revoke proofs of Bitcoin or ZCash addresses, but not Stellar ones. Any ideas why it is like that?

Start by reproducing the proof-revocation behavior from the Keybase GUI and CLI for the compromised Stellar address, then compare it with the available Bitcoin and ZCash revocation flows. Done means the old Stellar proof can be revoked and no longer appears as an active proof on the profile's Chain tab.
