AE Custom Field – Enter Field Key problem

hi, i try to make a template for my ACF Repeater, it is a link and i want to make it link to other custom field instead of static text (currently i am using static text). But when i select custom field and fill the key, nothing show up.

here is what i am talking:
static text: https://prnt.sc/rgqty9
custom field: https://prnt.sc/rgqttv

I try using custom field name/key, using AE – ACF field. But the same problem, when i want link it to custom field it doesn’t work. How to solve it?
thanks.
