131 has two building:part=yes pieces and no outline:

If you took away that tag on the last guy, I think streets GL would only render the center column, they talk about it in depth here: https://github.com/StrandedKitty/streets-gl/issues/3

In any case, the change I made was just to add an outline, and keep the two previous parts as the spec mentions.
