The two successful builds are for OS 3.x (d1_mini) and OS 2.3 (atmega1284p). The failed builds are for Linux and Demo, which should be built using the script build.sh and not in VSCode. Their profiles exist in VSCode mainly for the easiness of writing code using VSCode.
You can also select a specific build profile (e.g. d1_mini) in VSCode so it only compiles for that profile and not all 4 of them.
