Error occurs in the ui. Ammunition page. eroor pops up when I click on the arror to go to the next page(first 3 pages are ok -  4th page is when error occurs.).  Not a big issue. I can make the changes in the config itself without error.

That means something is missing inside the config, which means you must have removed something by mistake since it's all auto-generated.
The easiest way to fix that is to just delete the config and reload the plugin while the server is live. 

It won't reset the stacks or anything since they are already set on the server
