when I use this command to generate a iOS distribution certificate:
fastlane match adhoc
shows this error:
[!] Could not create another Distribution certificate, reached the maximum number of available Distribution certificates.
I check my certificate repo on the GitHub that only contains development certificate now.

Why I could not generate a distribution certificate? The certificate only could use in one environment? how to invalid the old development certificat? What should I do to make it work? But now I reinvoke the development certificate still show this error:
Only have one development cerfificate still tell me: Could not create another Development certificate, reached the maximum number of available Development certificates.
