Site-to-Site VPN with Certificates

Hey,

We used to use pre-shared keys but have recently switched to certificates, which all seems to be fine.

However, when I look at the summary of the VPN one both servers, they say:

Local:
Outgoing Authentication Method: Certificate
Incoming Authentication Method: Certificate and pre-shared secret (***********)

Other End:
Outgoing Authentication Method: Certificate
Incoming Authentication Method: Certificate

How comes. Why does it not say just Certificate for both Local and Other End? Interestingly, the pre-shared key is the same as it used to be when we actually used them. The settings for the VPN do not show the pre-shared key as being enabled, so where is it getting this value from?

Thanks
