Yeah, they wouldn't. The only time stats will carry over from one sheet to another is if the attribute names (in the html, not the visible label) are the same on both sheets. The data is still there. For stats that weren't in a repeating section, you could probably find them on the Attributes & Abilities tab. Anything from a repeating section is still part of that character as raw data, but won't be visible in any way since the structure of the repeating sections is totally different. If you want to change sheets, it is probably best to just rebuild your character on a new sheet so that there isn't the hidden data from the Megaverse sheet still attached to your character. It probably won't cause any problems, but starting clean might be best in the long run.
