ontimer block seems to break with expressions

[FAReTek1]

When using the ontimer keyword, it works so long as the input is only a literal value or a variable. However, once I place a + sign, the code compiles incorrectly.

Here is some sample code. it simply takes an input and waits for that long - 5 seconds using the timer functionality of scratch.

costumes "blank.svg";

onflag {
    time = "Infinity";
    ask "wait how long?";
    time = answer();
    reset_timer;
}

ontimer > time - 5 {
    say "beep! timer finished!", 2;
    think "...i pre-emptively beeped 5 seconds early..hehe";
}

However, when opening in turbowarp, the ontimer script is nowhere to be seen.

Upon inspecting the project.json file, i am greeted by the subtract block and the 'whengreaterthan' blocks having the same block ID.

That seems to be what causes the issue.
