Hi @marcguay
I’m afraid the acf/load_value filter will always return the number of total row instead of the array for the Repeater add-on and ACF free version.
Because you have the Repeater add-on, you should be able to claim the ACF PRO Personal license. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/upgrading-v4-v5/#how-to update. I suggest you use the PRO version instead.
If you still want to use the Repeater add-on, then please use the basic code instead of the advanced code.
I hope this helps 🙂
