Problem importing routes from kernel

Good day. I'm new to BIRD, and am having an issue that's hopefully a
simple fix.
I'm running bird 1.2.5-1 on Debian, installed via package. My end goal
is to use the BIRD process as a RTBH trigger via BGP.
Currently, I'm unable to get BIRD to import kernel routes into the BIRD
process, aside from the system default route. Interaction with the
kernel definitely works; when I peer up with my BGP neighbor, our edge
router with public BGP routes, they import and show up in the kernel
route table without a problem.
Here's my route table, and relevant sections of the BIRD config, and
outputs from birdc. Thanks in advance for any assistance.
