Can't Disassemble Power Storage CBMs

Can no longer disassemble Power Storage CBMs on most recent experimental. I used to disassemble them to craft MK II power storage, even on this same save. But now it says, “You cannot disassemble this.”
I have all the tools you should need, my computers skill is 6, electronics is 10. The developmental item browser still says it can be disassembled.
Did something change, or is this now intended behavior?

Disassembly not being possible is unintended, but crafting new CBMs from them is now not supported.
