[1.16] Model override in multipart submodel causes submodel to become invisible

[ChloeDawn]

Mod version: MC1.16.1-1.1.0.1

Attempting to apply an override to an element of a multipart submodel (in this case, the brewing stand#s stand), that submodel then becomes invisible. There are no messages or errors regarding this in the log. I also tried setting the layer to CUTOUT but it still had the same issue.
