Max Reactor size pulling from multiple locations?

[Chimearagrand]

I am running a modpack with the default max reactor size set to 16x and 16y in the config. I changed the max size in the config to to 20x and 20y, built a reactor that is 32x and 32y, and am getting two lines of errors whenever I right click it.

"Too big in x dimension, max size is 16"
and
"Too big in x dimension, max size is 20"
with just one click.

I pulled the big reactors jar file out of the modpack and downloaded the jar from the Big reactors site and dropped it in directly and the problem persists. Is this on the Big Reactors side or could something else be causing this?
