Shortcode not working

Nice to have this plugin to read a json from a external sourse.

But, i have a problem:

This is a example of my json (The format is fixed and cannot be edited.)

{"COLUMNS":["DATE","TITLE","DETAILS"],"DATA":[["December, 08 2025 00:00:00","Title example 1","Details of example 1"],["December, 09 2025 00:00:00","Title example 2","Details of example 2"],["December, 10 2025 00:00:00","Title example 3","Details of example 3"]]}

The test shows me all columns and all data:

When i use the automatic generated shortcode, it shows me only the columns, but no data.

[jsoncontentimporter apiaccesset="jcidb773e5" basenode=""]  COLUMNS:<br>
    {subloop-array:COLUMNS:3}<br>
      {COLUMNS.0} {COLUMNS.1} {COLUMNS.2}
    {/subloop-array:COLUMNS}<br>
  DATA:<br>
    {subloop-array:DATA:-1}<br>
      {subloop-array:DATA.:3}<br>
        {DATA..0} {DATA..1} {DATA..2}
      {/subloop-array:DATA.}<br>
    {/subloop-array:DATA}<br>[/jsoncontentimporter]

Result:

COLUMNS:

DATE TITLE DETAILS
DATA:

Thanx for your help!
