Can't add new icons to existent pack

[perigozin]

Trying to add new icons to an existent pack with the "+" button but it fails.

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'split')
    at eval (plugin:obsidian-icon-folder:184:46)
    at Generator.next (<anonymous>)
    at fulfilled (plugin:obsidian-icon-folder:28:58)

Also btw these icons I'm trying to add are the new ones from Remix Icon that haven't been included in Icon Folder yet. It would be nice if the packages could be downloaded/updated directly from GitHub or at least they were constantly updated internally with some kind of automation. Thanks.
