However, called BA today (issuing airline) regarding a request to move the ticket from the 30th of April to the 20th of May - same routing (MIA-LAX).
There are many things that can be happening.
The first is that the BA agent was looking for BA codeshares on the AA routes. The availability on the codeshare often differs from the AA availability. However for D and A classes to be zeroed out for the entire month is unlikely.
The second possibility is that the BA agent didn't understand the nature of AA domestic F. The fare, like many, does permit booking into A class on AA metal when D is not available. But for a BA agent, it is counter intuitive that a D fare (business) could ever book into A class (first). For them, it is like an economy class fare that lets you sit in business class: must be a mistake. The BA codeshares on AA metal are rewritten so that first class is seen as business class exists on AA flights when viewed as a BA codeshare. So that can throw a spanner in the works.
The reason they could not do this was because the available seats had to be exactly in the same fare class (guess this means price) as when I originally booked the ticket (september 2015).
That isn't true; but the fare as ticketed on the original date needs to be valid on the new flight. That might mean being in the same fare class, or another class that the fare allows.
The only option they had was to book me in economy class, with no option to pay the extra price difference between the fare classes either.
The RTW fares specifically do not allow per segment upgrading. You need to upgrade the whole ticket. [This is true for most fares.]
As a technical point, your expression "price difference between the fare classes" has no meaning. The whole ticket has a price, in this case it is decided by the fare DGLOB34. The individual flights do not, themselves, have prices. You cannot divide the fare into parts. Of course, you can find a price for the individual flights, by investigating what it would cost to make a ticket for each flight, but that has no relationship to the price of the ticket for the whole round-the-world journey.
