Help Please

Sorry I am new to this site. I have used Dolphin in the past but now am using it quite abit more. I am having an issue. Im playing Twilight Princess and found that in Hyrule Filed it drops frames to the point its almost unplayable. I learned from searching online that its a known issue and a fix is in place. My problem is I cant open the game properties for Twilight Princess and turn on the fix or hack. I typically open my iso by clicking on open then going to the folder I have put my isos in and loading it up from there. However I have seen most people have their ISOs already right in the folder of their Dolphin Emulator. So again I did research to see how this is done. Well I went to Config then Paths and attempted to add Twilight Princess and some other games. For some reason when I open the twilight princess folder there is nothing in said folder. Its completely empty. Yet when I go to that folder outside of using Dolphin the ISO is right there for me to click on. Ive also attempted to just drag the ISO into the box where you add a path. IT wont allow it. This is driving me crazy as I cant access the game properties to fix my lag issue. Can someone please help me with this. Sorry, I probably sound like a complete noob and I did search the forum for this issue and cant find anything on it. By the way, Im using version 4.0-8530. Thank you.
