Slow response time on LZW-30

Hi, I recently received a batch of Red dimmers and switches and am beginning to install them, and I’m running into a problem. I have two switches located in the same gang box. One I installed before having the updated open zwave config files, and one after I updated the files. The first install shows an average RRT of 238 ms, and the second has an average response time of 1118ms. Do I just have a bad switch, or is there something with the updated config files that are slowing things down? I’m running the latest version of HA in a virtualenv with a Zoos DST10 zwave stick.

I’ve attached a graph that shows my zwave network as well. Any help would be much appreciated.
