Issues faced after bumping version to 2.1.4

[plato-gno]

User f13r reports an incident in Gnosischain Discord after bumping version to 2.1.4

hello, I face several issues after updating my prysm gbc & validators to v 2.1.4:
level=error msg="config name=gnosis conflicts with existing config named=mainnet: configset cannot add config with conflicting fork version schedule" prefix=main
and
level=error msg="Failed to decode hex string." error="encoding/hex: invalid byte: U+000D"
any idea why. I didn't have these issues running v2.1.2
