One keyboard shortcut not working

[jankkm]

I am testing Rectangle Pro right now and I found something that might be a bug:

I use Hyperkey to map caps lock to ctrl + alt + cmd + shift and now I want to assign "hyper + q" to an action in Rectangle Pro but in the configuration it is not recognised so it cannot be saved. However, if I export the config, change it manually and then import the modified configuration file it does work.

"fillLeft" : {
      "keyCode" : 12,
      "modifierFlags" : 1966080
    },
