I generally delete the old sheet to remove any vestigial stuff, ya. You shouldn't need to, but it's safer and cleaner. The AC for my goblin is parsing. What part of AC isn't working for you?. Scimitar works for me Goblin

I see the problem with the shortbow: It is parsing the hit part as an action. This only happens in some cases based on wording and I didn't test any of those cases. I can fix this. Also the details tab isn't set - that's just a small text bug. Fixed and will commit soon.
