I want to remove my Network Active from my wordpress plug ins but cannot remove themes because it is still active.
It sounds to me like you have installed WordPress multisite. Perhaps this was an accident?
I typically don't recommend Multisite unless you REALLY know what you are doing and most people don't fall into that category, including me. There are so many technical challenges that for me it's just not worth it.
Here is a link with the instructions https://premium.wpmudev.org/blog/uninstall-multisite/
