Zombie Villagers coverted into wrong Profession

This bug happens in the 1.1.12 version of Xbox One Bedrock

Zombie Villagers are converting into WRONG PROFESSION

I have 32 (Lectern) scattered all across this village, (NO OTHER BUILDING) anywhere; and when I converted three zombie villagers, 2 spawned into Cartography Villagers, and 1 Butcher..
How is this appropriate behavior for zombie villagers? (trying) to find their profession.

I know before 1.1.12 they would be cured, than go to their profession building than be converted, but not anymore.
