mcpe realm-enchanted table not take player experince point as well

On realm,I have 30 level experince.So I want to enchant axe that cost 30 experince and 3 lapis lazuli.After I enchant,it only take 3 not 30.I think maybe internet problem but after my friend enchant same cost like me,only take 3 experince too.I weird,so I checked again and should take 30 but only 3.

Before this,I change to creative before I change to survival.
