DKIM signer not found error

[DerDennisOP]

Hi I'm getting a dkim signature error.

Feb 11 18:11:22 mail stalwart-mail[666]: 2025-02-11T17:11:22Z WARN DKIM signer not found (dkim.signer-not-found) listenerId = "smtp", localPort = 25, remoteIp = [ip], remotePort = 64228, id = "rsa-myexample.com"
Feb 11 18:11:22 mail stalwart-mail[666]: 2025-02-11T17:11:22Z WARN DKIM signer not found (dkim.signer-not-found) listenerId = "smtp", localPort = 25, remoteIp = [ip], remotePort = 64228, id = "ed25519-myexample.com"

My cloudflare has the record:

There are 2 Stalwart signatures configured. One rsa and one ed25519, both keys generated like the docs explain with openssl.
BUT only one DKIM signature is recognized by stalwart for the coresponding domain. What is going on? I have checked that the selector matches the id in the log and the dns record.
