Configs for Break Speed Aren't Working

[ChillyTiger]

Minecraft Version: 1.7.10
OS: Windows 10

I have Treecapitator installed on both server and clientside for myself, and no matter how many times I adjust the break speed it still breaks exactly the same. I'm looking to slow it down.

1.) I edited both the server and the clientside config files exactly the same. Still nothing.
2.) I used the config in-game in the mods menu, and made sure it matched the config files.
3.) I relogged after each new setting.
4.) I tried each new setting in both creative and survival mode, using an iron axe.
5.) For each setting I turned break speed in relation to tree height off and on.

I was cutting down standard spruce trees in the overworld. The only other mods I have that affect trees are FastLeafDecay and a mod that adds oranges to leaf drops. How can I slow Treecapitator down?
