Maradona Evo

I think so because the Maradona Evo's are only for grassroots promo rarity so once you change the cards color or design that automatically no longer qualifies for the Maradona sbc because you have changed the card RARITY. 

This explanation about the rarity change is not a valid argument. EA should have clearly warned players about this on the El Pibe de Oro page. There is no indication that applying other evolutions will disqualify the card for this evolution. Many players, including myself, have wasted hours grinding thinking they were following the correct path.

EA needs to either fix this or at least put a clear warning on these evolutions so players don’t waste their time and coins for nothing.

No, it is not clear at all. EA should not just list these requirements: 89 OVR, Special Item, max 10 PlayStyles, max 2 PlayStyles +. Instead, they should explicitly state: "Only players who have completed Dream Maradona 1, 2, or 3 are eligible."

As you can see in the screenshot, my card still meets all the "El Pibe de Oro" requirements even after applying other evolutions. EA is wrong here, and they should fix this bug or allow players to revert their evolutions.

Many of us have wasted a lot of time and effort because of this misleading system. EA needs to address this issue ASAP.
