Buildings disappear in ArcGIS online scene

[Ystad1]

I have created a number of 3D buildings using SketchUp and ArcGIS Pro which are stored as a multipatch. All buildings are visible in ArcGIS Pro and with the correct appearence. I have created a scene layer package and published to ArcGIS online. When I open the layer in a scene a number of the buildings are missing and a number have got white roofs and not the colour which I see in ArcGIS Pro. When I view the multipatch in a 2D map in Pro/Desktop/Catalog the missing buildings are visible. I don't think it has anything to do with the base elevation value as most buildings as visible.

Any ideas?

is there anything common amongst those buildings? common property? date created?

It was the buildings I created yesterday that aren't visible. I have just tried replacing a building in a new multipatch with a SketchUp model and publishing and it worked. Seems like my other multipatch is corrupt. For the buildings with white roofs it seems like I need to set a colour on the reverse side of the polygon (inside the building) so that it is not white when published on ArcGIS online.
