Is toNumbers supposed to mutate data?

I think I'm doing something wrong with the newer compromise/three. termList/out/etc. works great, but if I use them in conjunction with toNumbers the data seems to mutate in place.

Trying to do this:

const text_1 = "There are twenty-four apples and 12000 oranges on the table.";
const nat = nlp(text_1);

const number_of_numerical_values = nat.values().length;
// shows a length of two which is what we would expect so far so good

const termList_1 = nat.values(0).toNumber().termList();
console.log(termList_1);
// termList_1 has converted the number "twenty-four" to "24" but also has
// `"apples", "and", "12000", "oranges", "on", "the", "table"` in array

// rerun exact same command
const termList_2 = nat.values(0).toNumber().termList();
console.log(termList_2);
// termList_2 now has the expected array of just "3" 
// converted to numerical

I basically want to go through each numerically recognized "group" hence using the .values() command and use the toNumbers() command to reduce them down to the numerical number.

Picture to help indicate the issue:

@spencermountain Thanks for taking a look. Just wanted to add some information around this as well - near as I can tell it happens pretty consistently with out, json, termList, etc.

const nat = nlp('There were 24 apples and 12000 oranges on the table.');
