The most important things is air pressure in the beging and pressure in the end. Is the size of the the tank important at all for the SAC rate?

Why do I have to be in imperial mode?

I have read in the help how to create a Tank and add it to my dive. I can change the Tank size but I can´t change the working pressure. What is wrong?

I added 6 dives manually but the general SAC rate don´t work, look at the picture. I´v also added a pictures of all my dives.
