Tropical Fish don't spawn with black anymore

In the current Minecraft update in Bedrock Edition the tropical fish mob doesn't spawn with black as a secondary color anymore. I know naturally spewing black fish don't exist but you can have a fish with a secondary black as it's color, as you can have a lime-black spotty (just as a random example). I like to collect all the fishes and I'd appreciate if this was fixed because this wasn't always a problem and I've only noticed it recently.
