Pod configuration in kerbalism not working

[Hendrik]

Hello, I'm kinda new to Kerbalism and have been playing a bit over the last couple weeks, I finally got done with planes because I have GAP installed as well as a couple other mods that make the game more natural for progression, but I've finally started with sending up kerbals and not just probes and noticed that I don't have an option to configure my pods, I press the configure pod button and the window comes up and all that's there is the water recycler at the top and none at the bottom but with no little white arrow to change it, so I can't get a scrubber or pressure in my pods, am I missing something or is there a conflict with another mod
