ElvUI/Chronometer not showing in addon list

Hello all,

I am having troubles with ElvUI and chronometer showing up in my addons list. I download the file, and extract it to my addons folder for warmane 2.4.3 client. I have numerous addons that work fine and I'm 100% sure I'm uploading the addon into the correct directory. Anyone had a problem with addons not showing up but you still are able to see your other addons you installed months ago?
