Remapping replace (r key normally in vim) doesn't work

[ghost]

I have the following setting:
{ "before": ["y"], "after": ["r"] }, { "before": ["Y"], "after": ["R"] }, { "before": ["r"], "after": ["i"] }, { "before": ["R"], "after": ["I"] },

inside of vim.normalModeKeyBindingsNonRecursive

Pressing 'y' in normal mode doesn't replace the key highlighted, instead it does absolutely nothing!
If I remove { "before": ["r"], "after": ["i"] }, setting, the 'r' key works how I would want my 'y' key to behave.
