Default Exponent fully factored whilst only 74% known

Can someone explain why M397 is labeled as fully factored, when the details are:
Known prime factors (8 factors, 294.6 bits, 74.21164755% known):
Remaining cofactor is a probable-prime
Why wouldn't the exponent need to be 100% known before it can be labeled fully factored?

I also note that there are no PRPs attached to M397, which I would have expected with the mention of a probably-prime.
