Do you mean dials previews disappeared? or dials themselves?

Do you use EverSync or create backup manually on your PC?

When does this happen? FVD Speed dial must refresh all dials at least 1 time. 

You can't switch off groups (Default and +  on top)

You can't disable the last tab (speed dial indicator)
