[fixed]Loyal Retainers ineligible legend

[gnomefry]

Describe the Bug:

With Loyal Retainers in play during my pre-combat phase and two legendary creature cards in my GY, I can sacrifice Loyal Retainers and return one legend to the battlefield, but not the other.

Lady Caleria - returnable
Yisan, the Wanderer Bard - not returnable

I thought perhaps Yisan was not flagged as a legend, but I tested Karakas on him and it works. I'm hoping you folks can recognize what characteristic is making Loyal Retainers have a problem with Yisan.

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)

Holidays 2021 ad1a6f8 - gauntlet

What exactly should be the correct behavior/interaction?

Legendary creature returns to battlefield

Are any other cards possibly affected by this bug?

It's imposing an additional constraint of cmc greater than 3, ostensibly to advise the AI.
