SSD errors under NetApp E-Series 5424

Question

We're having some weird issues with our Storage (netapp e-series 5425) and a bunch of SSDs.

Technically they work fine, we can do all operations on it, whatever runs on it runs fine, but we keep getting these messages in the log (for all drives):

We tried to "decode" them using the documentation provided here https://kb.netapp.com/app/answers/answer_view/a_id/1072437/~/how-to-manually-decode-ddes-in-the-mel- but the message format simply seems to be different, so we haven't had much luck.

The firmware we have running is:

All the drives under it are:

We are at a loss on what do these DDEs mean, and we currently don't have a contract with NetApp for support.

Could anyone shed some light?
