Advanced Power Menu & Power Saver custom icons not working

[Former user]

Verizon HTC 10, stock ROM, S-OFF, bootloader unlocked, rooted.

Power Saver icons cannot be customized. (Frankly, I've never been able to do that with any version of Sense Toolbox since the Rezound, through the One Max, the M8, M9 and now the 10).

APM does not appear on long press of power button.

Yes, X-posed installed (other modules working).
