This asset comes with either Write defaults on or off depending on which FX controller you decide to merge.

This is significant because if your avatar is made with Write defaults ON in its gesture animations, importing the package that has it off can mess
with your gestures and they will get stuck.

You need to go in and check if your avatar has it on or off beforehand and install the the package that fits with your avatar then.
You can check by going to your avatars animation layers, clicking an animation box and seeing if Write defaults is checked on or off.

If you are either too lazy to check/still lost/have no one to ask because you do not know how, just install the one with write defaults on. It should work fine.
