As @dlang has said, you need to increase the extend chain length distance in advanced settings. I recommend 2032 because it’s a multiple of the chain pitch. When you do extend the chains, mark (permanent marker, nail polish, something) the link of chain that is on the 12 o’clock tooth. If you set the distance that’s a multiple of the chain pitch (6.35 mm) you should end up with one tooth of the sprocket back at 12 o’clock. So, next time you have to reset the chain lengths, you can set the sprockets to vertical and then place the marked links on the sprocket and then tell ground control to manually set the chain length. No need to go through the adjust chain process.
