named npc despawning - minecraft xbox one bedrock edition

my friend named a villager “curry” and so we put him in an underground house we used a name tag to call him “curry” . he had a bed light (not natural sunlight) and a lecturn however we went to our handmade villager / town to get emaralds but when we got back he had despawned . i don’t have evidence of him despawning as i didn’t record it just tweeted if it happened to anyone else.
