Bed didnt set your spawn

When i set my spawn with a bed, it didnt seem to save it and when i dies i respawn at worldspawn which is sucks.. it happen when i switch beds. ( bed not even broken + not get disturbed by hostiles when setting it ). When i set it again, nothing happens..respawn like normal

Situation i faced :

1. I went to trial chamber, set my spawn, died then respawn at worldspawn (didnt sleep)
2. I set my spawn at my villager trading place instead of my house. I died and respawn at worldspawn (didnt sleep)
