It shouldn't alter the SCH if you only moved parts around in PCB, that's why I suspect you changed something in PCB like picked a different part with the Inspector - parts are 3 view groups, so you can't just change a PCB footprint without affecting SCH because it's a new part -, added a part - it's a mightmare if you don't add it to SCH first -, deleted a ratsnest, or something like that.
I can't see much wrong with pin2 but pin 7 connects halfway in SCH.
