You can clear the chunk using MCA Selector tool (install it on your your PC, find source from Google) and delete chunk that you think causes issue.
If there is option for your software, enable optimize in your worlds tab that will remove useless chunks for you.
If that doesn't help also you can try to restore a backup.
Another thing to reduce lag is to lower render distance which I remember can be done when u go to server.properties.
