Okay, so I used your tip (very useful tool, thank you for letting me know about it btw), and I found the files. I tried editing them by removing the lines of code I highlighted in the attached image. It gave no result, the menu was unchanged. I made sure the cache was off and cleared my browser cache, even tried it on a VPN so I don't think it's a cache issue, I think I probably must be missing something. I freely admit, I'm no expert at this though, not even close, so I rank the chances of me missing something fairly high. Any help would be very welcome
