Possibly one is the Bishops Transcripts details (General)

There are many original Parish Records which are missing or illegible and because of this we have filled the gaps with the details that are in the Bishops Transcripts.

It appears that both of the records you mention refer to the same marriage but because the surname of the bride is different on the entries we have ended up with two entries for the marriage.

I will ask Graham the co-ordinator of the Parish Record Project to check if my guess for the reason of having two entries is correct.
