Hi there Ernst,
I wanted to see what my Birth Spread is using Sidereal Ayanamsa and it is identical to Tropical. So with C of T birth spread as Sidereal many of my planets are in the wrong card. My astrology chart is correct as Sidereal . So did it just default and something else needs to be changed for the Cards of Truth ? I just unclicked in "Calculation Options" the "use tropical Rasis ..."
THe software does not use sidereal options in the card spreads, so if you set those, its still going to show cards with tropical. The new version of kala will do that.
