[Fixed]-Could not parse the remainder: '((records_list.1.key.5)' from '((records_list.1.key.5)'

The if tag does not support parentheses. From the docs:

Use of actual parentheses in the if tag is invalid syntax. If you need them to indicate precedence, you should use nested if tags.

In your case, the parentheses are not required, so just remove them:

{% if records_list.1.key.5 > 0 %}
