They appear again because the walls are updated and their block states are changed to normal and intentional ones, making it visible.
Some block state combinations for walls cant be obtained normally and they werent made to have proper models and hitboxes.
In this case the wall is just invisible and has no hitbox.
The walls aren't actually deleted, their block states convert so everything is false
resulting in the wall being invisible.

This bug isn't a duplicate of MC-239856 for 2 reasons:
much different version range of this bug occuring; MC-239856 occurs by updating from versions around 1.11.2 (probably just pre The Flattening) to current version (maybe few snapshots back) while this bug occurred always by updating from version before 17w47a to 17w47a or higher.
different affect on vines; MC-239856 sets all vines' "up" state to "true" while this bug makes all directionless vines just break.
This report is invalid as this project is for bugs for Java Edition
