Hi, it seems that setting instructions “below fields” isn’t affecting sub-fields of a repeater but is affecting the repeater field itself :/
ACF 5.3.1
WP 4.3.1
notice “asdfasdfa” which is the instructions set for the repeater field itself

Ideally it would be nice to be able to control the two contexts individually. I think most often developers would put instructions for repeaters under the label so it doesn’t get pushed down, but I could see a desire for “below fields” for the sub fields
Thanks!
I can’t say if this is intended or not, but it is the way it’s working. I’ll flag this topic for the developer to take a look at when he has time.
Has this ever been solved? I’m still facing the issue.
