Hello Klaus, team,

I am a full subscription user - and have created customized lists of radicals by order of frequency.  In the first batch of 20 I can train the whole list in Audio Trainer - but when I try browse and practice in Writer, only 16 of the 20 radicals are available.

This occurs in almost almost all of the lists of 20. 

 Does this mean that you have missed some radicals in Chinese writer and is this intentional? The 4 missing radicals in the first batch of high frequency group of 20 are radicals " walk" "roof" "grass" and "silk" - and so cannot practice the strokes for these radicals in this fist list.  Please explain - thank you!
