F5 key mapping to ⌘R doesn't work with a specific keyboard


I use BetterTouchTool to make F5 reload webpages in Chrome. It works in all my other keyboards but not when using Keychron K8.

I have it set to work on all keyboards.

In my Mac settings, I have "Use F1, F2 etc. keys as standard function keys" ticked.

Any help is appreciated.
