Inverted Extruder Sensors
All 5 extruder sensors are reporting 1 "ON" when empty with no filament, and 0 "OFF" when filament is loaded. This has effectively bricked all the extruders, which now fail to load or, if I trick the extruders to load, think there is no filament present when the filament has been loaded.
I don't see how this could be happening other than in the firmware. Has anyone else run into this problem?

Fixed this by exploring Settings. There is a Tool section, where filament sensor calibration can be engaged per tool. This may or may not be needed after disassembling and re-assembling the extruder. In my case, 2/5 extruders needed re-calibration. You have to disassemble and re-assemble the extruders when adding the official PrusaXL enclosure.
As an aside, if you get one of the unofficial PrusaXL enclosures, your 3D printed extruder components may not perform in the heat. Although costly, the official enclosure does the things, without the bugs. Do wish I'd have been notified I might need to recalibrate the filament sensors, as I only conceived it might be something that can be re-calibrated only after ruling out user error by disassembling and comparing a working extruder to a non-working one.
RE: Inverted Extruder Sensors
I have confirmed this is a bug with the extruder firmware by unplugging the sensor. Once the sensor is unplugged, the extruder sensor registers as "ON" and believes there is filament present.
Is this bug fixed?

Fortunately, I was recovering from abdominal surgery with an allergic reaction to the muscle relaxers and baby sitting my toddler, so it wasn't too big of a hassle.
