NPC’s keep disappearing after I unload the chunk (Citizens plug-in)

As soon as I unload the chunk where the npc is and then re enter it the npcs are invisible and will not show up unless I either relog or unload the chunk again, does anyone know if there is any way to make it so this doesn't happen? I’ve tried multiple citizens versions also which do the same thing.
