BIGTREETECH SKR V1.4 not recognised in Marlin 2.0.0 VSCode

I'm trying to flash the firmware in my Anycubic Kossel and am in the process of configuring all the code. In the #DEFINE MOTHERBOARD area, my board doesn't get detected, giving me the error message: "#error "Unknown MOTHERBOARD value set in Configuration.h" under 'Marlin\src\pins'.

The SKR V1.1 and 1.3 get detected, however, under the labels BOARD_BIGTREE_SKR_V1_1 and BOARD_BIGTREE_SKR_V1_3.

Did I just download an outdated version of Marlin? Any help would be greatly appreciated.
