is this plugin compatible with the cache plugins?
Who knows?
But when I deactivate WP Fastest Cache, counter correctly deducts.
Now I have plugin Autoptimize (kind of cache, js, css) and counter is correct.
Autoptimize is not a cache plugin.
Please contact the developer or you can try another cache plugins and try.
I was right. You just have to turn it off Cache System in Settings.
This is cache like cache in browser. He keeps the saved state to load the page faster.
The same is true for changes on the wordpress website. You have to disable the plugin cache, because it does not update itself.

The plugin is not compatible with cache plugins.
“Clearing cache every 1 hour” reduces the performance a lot. You can use like that but I don’t suggest. The developer of plugin should count via Ajax.
