SSH key goes missing after bitbucket/atlassian account merge.

I previously registered an SSH key on my bitbucket account. After merging into an Atlassian account, the SSH key no longer appears in my SSH key settings. However, it seems like the key is still registered, as I cannot re-register the key (it citing "Someone has already registered this as a deploy key." as the reason).

This is pretty serious, as I no longer have control to deactivate this SSH key in the case of a compromise.
