Video showing impossiblity of adding any shapes other than the first in each
category

libreoffice | package | 7.0.0.0.beta2-1.1 | x86_64 | openSUSE-Tumbleweed-Oss

No matter what shape you drag from the "Gallery" in the sidebar, only the first
image in each of the categories is installed. The multiple categories in the
Gallery are from extensions I have installed from
<https://extensions.libreoffice.org/> (they were part of 6.x but have been spun
off as extensions for 7.0 Beta 2).

Tested on Impress and Writer.
