I have a new UM3. I also purchase AA/BB .8 printcores. The problem I'm having is when I switch the printcores from AA/BB .4 to AA/BB .8 the printer seems to recognize them. But when I go to the slicer Cura, it does not switch to the AA/BB .8 printcores.

When I click on 'Print core & Materials' i see 'automatic:BB 0.8', but it does not switch to 0.8 it stays on 0.4. I've done a reset, calibration, added and deleted the printer in Cura multiple times. And I get the same thing. I've even gone up to the 'Settings' menu, and I get the same.

Could I get help please?
