Accumulator not showing accumulated energy on Jade, however, energy still goes through to machines

nvm seems to be working now i dont understand what happened

nvm, again. after testing more, it seems to not display any accumulated energy for a while, then it just starts going up. I dont know what causes this, but after a while of it accumulating and displaying 0, it starts accumulating normally... I have to say that even when it says 0, energy still goes through.
