Broken Valve Spring - only 5000 miles

I'm aware of the quality issue for valve springs fitted to original 3.0 SC, but has anyone else had a failure of a fairly new spring?

I have a set ordered from our host 2 years ago; they've done approx 5000miles... found a broken outer on cylinder 6 intake today.

Not sure if I should replace all 12 sets, or just the 1 set? The ones I ordered were the generic OEM ones.. not Porsche genuine.

Open to guidance.
