Middle name and surname appearing together on passenger info

Hi - I have a flight booked this Saturday (booked through Booking.com) for me and my brother, London to Vancouver.

We noticed today on the BA site that our middle names are tagged onto our surnames without a space - eg. Jane SophieSmith and John MichaelSmith. The booking confirmation email is correct however - 'Jane Sophie Smith'. I called BA customer service and they weren't particularly helpful - just said that as we booked through a travel agent (Booking.com) we need to contact them and request the change.

I will contact booking.com but just wanted to check here if anyone thinks this will be a problem at check-in or has been in the same position?

It seems like a trivial thing but obviously want to avoid any issues on the day! Thanks :)
