It seems that in the online interpreter : always filters by value, rather than by ID if the : is preceded by an @ symbol.
Minimal program that shows the problem:
.-#1@:$"Whoops"
This should print nothing. On TIO and in the offline interpreter, that's the observed behavior. In the online interpreter "Whoops" is printed.
