Knob widgets with errors inside. TD 099 16660 On Windows 10

I just put a Knob Widget form the palette (even endless or fixed) and I find this two errors inside them…

Second error

Hi, it looks like the default font for Widgets “Open Sans” is not installed on your system.

If you go to the Help menu, Help > Browse Samples > Fonts then you will find Open Sans font which we distribute with the TouchDesigner installation. Please install these and the warning should go away on restarting your file. We will look into why the issue is happening in the first place.

Hi Simplo,
Just wondering if you found the fonts in your Samples directory? If they are missing that could be the problem as installing them is not required actually.
