Custom library entries save, then go blank or "Untitled"

On Echo's account, about five custom (manually entered, not clipped) library entries in the Ballantine project saved, displayed correctly, then went blank or showed as "Untitled" in the Unassigned group after navigating away and coming back.

Details:

• Entries had vendors assigned when created (one was Monica Kirk, seamstress labor; one of hers survived, one disappeared)

• Created yesterday, roughly 2-3pm Echo's time (Pacific), which overlaps a production deploy

• Echo clicked the update prompt when it appeared

• It happened again after she took a break and came back

Expected: saved library entries persist. Run a debug session on library save, with focus on custom entries, grouped view, and saves made during a deploy window.
