Having an issue with zones

I run TruePVE on my server. I just set up the Arena plugin from ChaosCode. I set up two zones where the arenas would be and allowed PVP. It worked at first. Later, after doing some other things, I noticed that neither of the zones I set up were working. I determined this by the fact that I could build in the arenas even though building is specifically blocked. I decided to create a new zone as a test. I created it, then set NoBuild. I confirmed in the data file that NoBuild is set yet I can build in the zone. So, any clue as to what is going on? This is my data file:

This is my list of plugins. Maybe one of these is known to conflict with Zone Manager?

As a logical trouble shooting step, I unloaded all mods with the exception of the Zone Manager plugin and I can still build in an area I have confirmed is flagged as a no-build area. Is the plugin broken? Did something in Rust change to cause this?
