how can I eliminate circular role rempapping of standard structure tags (eg document,H1, span) in tagged pdf exported from Writer

Evey tagged pdf I’ve generated from Writer ODT files shows the same errors when checked with the PAC2 accessibility checker. Standard structure types are remapped to themselves, which then generates corresponding circular mapping errors.

I’m using LibreOffice 4.2 on a 2012 Macbook Pro with on MacOS 10.8

I think, that it cannot be solved from a user level. You should write a bug report about it to get attention from a developer.
