This isn't *quite* true. There should only be copper pads in the Gerbers on
the layers that intersect with the layers of the blind/buried via.

I get the following drill files for connecting the copper layers with

Based on your original message, this would be the first thing I'd check.

On each copper layer the via goes through, there should be a copper "pad",
