Hello @jcduewekeperez,
Thanks for writing to us.
I tried to access your site but the given login details are not working. Please recheck and send us again.
To hide the empty field I would suggest please have a look at this doc to learn more about how to set the condition. You need to retrieve the ACF field value by using dynamic content code and then compare the value if it is not empty.
For the terms that you have listed, regretfully there is no option to remove the custom text if there are no more terms available. It would require custom development I would suggest you please contact a developer who can assist you with your concerns or you may subscribe to One where customization questions are answered. Please note that we don’t provide custom development support. it is out of the support scope.
Thanks for understanding.
