Remove Speed Camera on N313 - Ommegang Oost, Westrozebeke

Hi,

I’d like to remove the speed camera pointing north, but can’t seem to save that change (no permissions error).
The camera pointing south is still in place, the one pointing north got removed (or was never there?).

Any suggestions on how I can avoid this error message?
