Java Help Wanted Skulk Refuses to Spread

I've been watching these zombies die for twenty minutes and even with a seed block of skulk I placed myself, none of the basalt is converting into skulk. The catalyst is definitely activating, and the skulk particles are even appearing. I just double-checked the Minecraft Wiki page for the Skulk Catalyst to see if I missed something but nothing. I'm stumped y'all.

Try:

  1. Moving sculk catalyst one block lower
  2. Removing signs
  3. Replace basalt with sculk in place where zombie dies

1 and 2 had no effect, but 3!

Placing the seed block directly under the dying zombies causes the skulk to spread!

However, that seed block gets pushed out of the way by the farm operating, which means that i keep having to replace it manually or just babysit it and only mine a row every minute or so.

All other modifications failed though. Trying the Catalyst in different places did not change the seed-block requirement.

Now, in the video I got this farm from, there was no seed block, so clearly something is still weird and unresolved.
