Searching an icon doesn't work anymore
Hi! I love this pllugin, but in the last days I'm getting some issues in using it.

I'm working on a project with the Material Icons set. I'm not able anymore to use the 'search' function when I'm in the grid view (Grid Insert > Material).
I'm noticing that now, whan I insert n icon, the label of its layer is not called for example "material-arrow-forward", but instead "<MOMethod: 0x60800c028640 : target=0x60000ceffe80{     created = 1;     id = "arrow_forward";     name = "arrow_forward";     unicode = e82e; }, selector=name> - material".

I've tried to re-install the font, the bundles, the plugin, but nothing changed.
I'll attach two screenshots here :)
