Falco's Prop Protection forgets all blacklisted items on restart

All of the sudden my entire blacklist on my server has disappeared as well as tool restriction, so as you might guess, it’s gotten chaotic with people using turrets, dynamite, etc. I’v tried re-installing Falco’s Prop Protection and I even truncated MySQL blockedentities table assuming it had too many entries. I started blacklisting again, but every time the server restarts, it drops all of that and I have to blacklist every prop and tool over again. I have some tools I definitely cannot be having players use and until then I have to lock my server. I remember this happening to me before, but it was literally a year ago and I don’t remember what we did to fix it. Is anybody familiar with this problem and can help me?
