first, thank your for this report!
we are sorry for that non-working part!
the author of the mod didnt update his mod since (before) v1.0, so such glitches may be possible!
as this is no gamebreaker, we still have it chooseable in modpack, but in future releases,
we may disable this selection, or if one comes out, update it to a new version!
edit: mod updated by dev and running
thx for using our modpack,
