Same experience here. The system adjusts the surname to show with either a space or no space (i.e. just merging the two names into one continuous string).
It doesn't seem to cause any problems with matching to your EC account or with immigration details.
The only minor hassle we have experienced is when trying to retrieve a booking, you just have to try both options.
