Error when using Material Button

Getting this error when I drag drop Material Button or make any property change when connected to the Companion.

Are you using the latest version of the companion?

Yes, on the beta server.

@Tmohank The error is probably due to the Font Typeface, surely you used a Material Icons, now instead of Material Icons it says “4…”, and it doesn’t recognize it, could you verify if it appears like this?

I have the same problem, it also happens with the labels…
