Remove Object From Array Not Working

OK this seems simple, but I am running into an odd issue. I have a really basic function that should just remove whatever object it is passed from the array.

Here is the function where I lookup the record and the object I want to remove.

Now when I go and run this to try and remove number 3 from the array.

For some reason on the input for updating the variable, my users_id which I wish to remove, which you can see on the screenshot above, is just gone.

Any ideas?
