I really wouldn’t be able to say why it’s not working, I don’t know what those other functions are.
I would start with creating a similar group in ACF and exporting it to PHP and then making sure I have my local field group set up properly, all the right values and required keys and such. Generally when I’m putting field groups into php that what I do anyway. I build the field group that I want and make sure it’s working properly and then I export it. At that point I pull it apart to do anything dynamic that needs to be done with including or not including certain fields and make any other adjustments.
