Using F13-F24 as hotkeys

[Keruberus]

Hi, I've rigged up a numpad using luamacros to output the F13-F24 keys. That said, Only F13-F15 are working as valid hotkeys in PrprLive, the rest do not register. Also, even when I try to write the .prprlivejson manually with additional keys (Ctrl+Alt+F13) it merely reads F13. I've checked my luamacros program works properly using a keyevent viewer.
