Why View Parser Filter not working on Loop Substitutions ?

I'm having the same issue.
I have a value inside an array so when I'm trying to use filter, Parser shows the "brute code". This happens when I call filters with parameters, like number_format.

Code:

{array}
  {subarray}
      {value|number_format(3)}
  {/subarray}
{/array}

This doesn't work. Will show same code on the view.

On the other hand if I use "abs", works with no problem.

Code:

{array}
  {subarray}
      {value|abs}
  {/subarray}
{/array}

Shows as expected and getting transformed data.


Any ideas why is this happening?????
