Why is "New Eye on the Universe" locked? Nova: Season 50, Ep 4.

Nova often has placeholder text, which is later updated. I'm not 100% certain which of the two blurbs (below) is most up-to-date. However, the first is more expansive and, I contend, better text for a description. I'd like to swap it out from the current description blurb. Is there a reason Ep 4 is locked where other episodes of the same season are not? Please note both blurbs exist on various PBS/Nova official -or- affiliate sites. I've included links for both.

#1 Replacement text I wish to use — Ep 4, description blurb from Nova Site:

In July 2022, NASA’s James Webb Space Telescope released its first images, looking further back in time than ever before to show our universe in stunningly beautiful detail. But that was just the beginning: With tons of new data and spectacular images flooding in, Webb is allowing scientists to peer deep in time to try to answer some of astronomy’s biggest questions. When – and how – did the first stars and galaxies form? And can we see the fingerprints of life in the atmospheres of distant worlds–or even within our own solar system?

#2 Current text — Ep 4, also a description blurb from other PBS affiliate sites:

Join scientists as they use NASA’s brand new James Webb Space Telescope to peer deep in time to hunt for the first stars and galaxies in our universe, and try to detect the fingerprints of life in the atmospheres of distant exoplanets
