MFP Tech Help

I seem to have two separate but linked accounts for myfitnesspal; donaldarmstead1 and Donaldarmstead1. I'm not sure how I did this but I think it has something to do with starting my account years ago but not really starting to use it until this year. Anyway, donaldarmstead1 has lost 8 pounds (started a few months ago at 280) but Donaldarmstead1 has only lost 3 pounds (started a year or more ago at 275). It's not an enormously big deal obviously, just annoys me. Thanks in advance.
