Can't change airdrop marker node ID

[ArmstrongReal]

When I try to change the airdrop marker ID to anything it simply says "null". If I change the id and click off the marker the ID resets back to 0. and the airdrop wont work in-game

If I look at the markers on official maps it looks all fine until I try to change the ID which results in null again.

I've validated my files, and tried placing them on different maps with no luck.
