Carbon wheel loose threads...like a t shirt unravelling

I have some DT Swiss ERC1400. My first carbon wheels they are 2 months and 4000km old.
I am regularly finding very thin loose threads of carbon. I can cut them no problem. If I pull them it is like pulling a loose thread on a shirt...could pull for ever I think. They all seem to have the source of the loose thread beneath the tyre and on the exposed surface all seems fine.
Is this normal? Or are the wheels faulty?

Additionally you say 2 months and 4000km, that’s a daily average of 66km, chapeau if that’s correct!

Yes, had the same with them myself.
Their reply...send the tyres back to Germany for analysis
My reply...send me some tyres so I can keep riding and a cheque for the postage
