I updated today to 2.7.1.62 of studio and filaments 3 and 4 on my H2C are blank. The drop down column is all empty with nothing to select. I have 2 AMS units hooked up and 5, 6, 7, 8 are all selectable. I’ve restarted the software several times with the same problem. There is filament in those slots and it shows up on the printer.
MacOS network plugin install loop persists on 2.7.1.62. Also on Golden Gate beta 1.

I can no longer sync my filaments. Normally, a window opens where you can choose to overwrite or adjust them. Instead, I get an error message.
I am having the same issue on two A1s. Spools 3 & 4 have vanished. Restarted my MAC, and both printers. Updated firmware and newest version of Bambu Studio. The spools show when I select device but when I go to sync they are not there. Also, I am unable to paint an object. This is a serious issue. On both A1s I can select an object and paint by line, but not flood.
I’m having the same issue with Windows 11 and P2S 
I have to click on edit preset and change on the list, but sometimes it shows my AMS filament 3x
