I have been adding files for several months on 3D Content Central via the excel template. For some reason the part number doesn't always display in the model listings, see

3D ContentCentral

I've looked through the report from content manager page and there doesn't seem to be a pattern. The first 20 uploads on 25 Aug 2014 all have part numbers but the last one in that same upload doesn't. From then on only 6 out of 50 have part numbers visible. On 18/8/15 I uploaded 3 models from one spreadsheet - 2 have visible part numbers and 1 doesn't.

None since August 2015 have had part numbers visible.

It doesn't matter if it is an assembly or a part, both have worked and not worked at different times.

Then if I click a model from the listing without a part number, the part number shows at the bottom left box under specifications as it should.

I haven't changed the way I'm uploading and there doesn't seem to be a way to hide/show/add this part number field when I try to edit the content.

Am I missing something?
