Claiming PIP Mistakes Made At Welfare Appointment

I am claiming PIP for my health conditions and I have also been bereaved recently so when I was offered help from my housing association’s welfare department to fill in the claim form I said yes. I had the appointment yesterday but there are mistakes – what’s been written is not what I said and there are spelling mistakes. It’s unusable the way it is so this has added even more worry. Is it possible to get another claim form as I would rather they didn’t see the contradictory things the other person has written and I can’t erase/cover them. Thanks.
