Generated document is false after mail merge with conditional IF

Hi, when we perform a simple mail merge from a document that contains conditional IF, the result in the generated document completely false.
I attached the document with its data source.
Thank you.

Hi,

Unfortunately, at the moment the evaluation of conditional statements in fields is not supported. Please try to move all the logic from the document to the code. We will surely implement the field evaluation engine later.

Thank you for your answer.
Do you also have a time estimate of when this function will be available?

I think it will take several months, not sooner unfortunately.
