Really depends on how you have entered the flights in your logbook - by that I mean any remarks and/or instructor signatures.
Attempting to alter your logbook now that it has been seen by the CAA is tantamount to serious fraud and is not a direction that I would recommend anybody to go in.
I hope, for your sake, that I'm wrong when I say that the way you appear to have entered the flights (both dual and P1) highlights to the authority that you had an instructor on board - so you are screwed.
I saw another CPL candidate, at a different school (I've worked out where you you did the JAA CPL) who had over 600 hours - of which only THIRTY MINUTES was genuinely flown solo, including the full PPL course. I was amazed to discover that it was not only possible, but legal.
You have encountered a problem generated by flying within a system (FAA training) when training towards a licence and/or rating that they know, or care, little or nothing about. I would suggest that both schools you used were by a river - one FAA with "links with a JAA school", one JAA approved.
