The Economic Liberals are all also Social Liberals because being for gender, race, sexual-orientation (and so on) Equality does not impact the only form of descrimination they defend: wealth discrimination.
Further, very few of the supposed modern day Social Liberals are not just Economic Liberals wearing a different mask: you can tell it because whilst they loudly criticize gender, race and sexual-orientation discrimination they literally NEVER even mention Wealth Discrimination, much less criticize it - it makes very little sense for one to be for Freedom of human beings in society and rage about how for example people's treatment at the hands of the Justice System differs depending on their race and yet be totally silent about how people's treatement at the hands of the Justice System differs depending on their wealth, especially as the latter is vastly more prevalent than the former - surelly any difference in the way Justice treats people is unfairly reducing the Freedom of those discriminated against and the principle of harm reduction dictates one goes after the thing with the biggest impact first or at least more intenselly that those things with more restriced impacts, hence outside countries were the other kinds are trully gigantic and with massive outcomes (Israel, Apartheid South Africa and so on) they should be raging even more against wealth discrimination than against other kinds of discrimination.
As I see it, the only real Social Liberals are Social Democrats, and those are mostly gone in the present day, when even the supposedly "Thinking Left" who claim to be Social Democrats loudly parrot Identity Politics whilst clearly refraining from talking about wealth discrimination and even when they talk about the latter, its much less often than the former even though the dimensions and consequences of the latter in pretty much all Western Democracies are far more massive than the former, to the point that average life expectancy for the poor is decades less than for the rich.
