Plugin Still Running After Import?

Hi. I purchased all your addons for the CSV Importer. I imported 16,000 products. I had succesfully imported 6,000 products but then server kept timing out and I had to keep making the CSV smaller and smaller until a few hundred. So took a few imports to get them all in. Since then my site is running slow. I have tried optimizing it as much as possible with cleanups for the database, cache, etc.
Question for you…. Using the P3 Plugin Profiler after a scan it is showing that CSV Importer is causing 83% of the load time which is about 4 seconds the other half is woocommerce. Why is CSV Importer still coming up as the plugin that is running and causing the site to be slow when the import is already complete?
