Abrasive Material and High Flow Nozzle Issues with Prusa Connect

[chris-5634]

Description of the bug

When trying to export gcode through prusaconnect, warning that filament is abrasive and highflow nozzle is recommended appear, even though settings are checked off.

Does not impact uploading file, but can be confusing.

I have access to MK4 with MMU and without, along with a 5T xl, issue not present on regular MK4 when sliced as single extruder, but remains on the MMU printers and the XL.
