Eazy Product Options & Variant

It was difficult to set up so that I uninstalled. But some functions are still remaining and affecting my shop operation. I really want to remove it all.
Why does the app. work in that way???

I contacted their support team, which gives me very detailed instruction. As I liked their way to provide support. I decided to reinstall this app. With live chat (help) I was able to successfully created options I needed. Thanks.
