The bug
The top of sandstone wall and red sandstone wall are the side texture instead of the top texture. This has nothing to do with the new textures, it's just that the side texture is applied to all faces, which is a mistake.

Still an issue both in 1.14.4 and 1.15 pre2
Confirmed for 20w06a.
There are two possible fixes for this: one is really easy and not really a fix, which is using the bottom texture instead of the side texture. The other one requires creating "template" models for walls which support 3 different textures and then using those templates for sandstone and red sandstone wall models. These fixed models are included in the attached resource pack.

I can still reproduce this in 1.20.1. @Alex perhaps you're using a resource pack?
