Is there a way to pay the difference and not have to buy the same exact thing again
Absolutely, just do what pocketmouse said. Everything you purchase here counts as credit towards relevant larger purchases. For example, if you buy just the subclasses from a book, that money will count as credit towards the whole book.

Is it because I have the $20 compendium only version? I thought it would allow me to use the classes in my sheets
Nope, “compendium only” is a read only version. The $30 “full version” is required to use content on the character sheet.

Yes, if you go back into the marketplace it should show a lower price now.
