How do I remove an app I previously purchased off my gmail account?

http://forum.xda-developers.com – Hi I'm not sure if this has ever been asked. I'll try to make it as simple as possible and I'll post a screen shot. So when I go onto my play store and go to my apps it shows installed apps and when swiped to the left it shows all apps. There are some apps that show on my all apps section that I don't want showing anymore and I can't long press them to delete them off my gmail account. Is there any way I can remove them? I have ES file. Can't I do something in ES files and get into my system files for the play store to remove them that way?? Any advice would be really great. Thank you in advan (HowTos)
