Started a new sandbox game in a clean install, no mods.
Installed Nertea's Cryogenic Engines, which bundles B9PartSwitch and patches the stock fuel tanks to be able to hold LH2.
In the VAB, configured a stock FL-T200 fuel tank to hold LH2+O instead of LF+O, and placed it on the * launchpad with a probe core on top.
Quit the game and installed ConfigurableContainers.
Went back to the fuel tank on the launchpad. It now had an empty resource bar for LiquidFuel, in addition to the full ones for LqdHydrogen and Oxidizer.
Opened CC's "edit tanks" window. It only showed capacity for LiquidFuel and Oxidizer, no LqdHydrogen, despite the tank's right-click menu showing LqdHydrogen actually in it.
Quit the game and deleted ConfigurableContainers.
Went back to the fuel tank on the launchpad. Now it had only the LiquidFuel and Oxidizer resource bars — the LqdHydrogen had vanished.
Bottom line: CC has its own built-in idea of what resource types a tank holds by default, and it does weird things if some other fuel switcher has already changed what a particular tank holds. I don't want it doing those weird things in my career save, where I have vessels in space that've been configured with other fuel switchers.

I just did a test and here's what I observed:
