I have created a jail and now my prisoners can leave and when they die they no longer stay in jail. Is this due to zone manager getting updated and jail not being updated?

Good day, I am not sure if I am in the right place or if there is anyone with the knowledge to assist me. I am running the Jail plugin for Rust on my server. It sometimes works and sometimes doesn't. When it works the player can't leave but when they die (from hunger or any other reason) they can respawn anywhere and they are not returned to their cell in prison. I have very little coding knowledge but from what I understand and what I have read in the plugin it should work but I'm not sure of the recent updates in ZoneManager may have broken this plugin and was wondering if anyone could help me figure out why it's not working the way it should. The plugin dev seams to be unavailable to update at this time and was hoping to do a hotfix to get it working again so players can not leave the jail till their sentence is over. Thank you in advance
