Icedove GPG unsupported features

Hi Trisquel,

Icedove says:

Some of the imported secret keys advertise an unsupported feature. If
you use such a key as your personal key, correspondents may send you
emails or public keys in an incompatible format. This affects imported
secret keys with the following fingerprints:
631CC434A56B5CBDFF21234697643795FA3E4BCE.

My key looks like

pub   rsa3072 2023-06-29 [SC]
      631CC434A56B5CBDFF21234697643795FA3E4BCE
uid           [ultimate] Caleb Herbert <name at domain>
uid           [ultimate] Caleb Herbert <name at domain>
sub   rsa3072 2023-06-29 [E]
sub   rsa2048 2023-06-29 [A]

Will this be an issue in trying to use GPG?

Thanks,
