bug: Startup Error Message

Did you check docs and existing issues?

[X] I have read all the which-key.nvim docs
[X] I have updated the plugin to the latest version before submitting this issue
[X] I have searched the existing issues of which-key.nvim

Neovim version (nvim -v)

0.10.0

Operating system/version

Pop!_OS 22.04-LTS

Describe the bug

Since the new release, every time i open nvim, i get an error message linked to which-key, when i proceed with :checkhealth which-key i noticed that the ERRORS are related to "" keymaps (but only those added with require("which-key").add{}) or WARNINGS to keymaps that have similar bindings, but not repeated (overlapping). My problem is actually about the startup message (which i believe is only connected to the <leader> keymaps errors), not really about the :checkhealth output...

Steps To Reproduce

Add keymaps that use the <leader> binding
Set keymaps that have similar bindings (but not the same)
:checkhealth which-key

Expected Behavior

No errors with <leader> binding, which would lead to no error message on startup...
