Pricing setting is missing or decay looks flat

Time weights is missing. It appears only with Option time on Trading. Switch Option time to Trading in Settings → Trading.

A stock’s weekend decay looks flat. By design. Single stocks, and symbols outside the S&P, Nasdaq and Russell families (DJX, VIX), use flat fallback weights. See Option time.

Rate unavailable. Risk-free rate on Auto uses the last rate it read and says when it could not refresh. Choose Manual to set the rate yourself.
