displaying ACFs in a headline field

Hi,

Firstly, apologies if this is obvious and I really have searched high and low on the forum for an answer.

I want to display some custom fields within a Content Template element.

This is would be using a custom post type called Projects.

I have the pro versions of Generate Press and Generate Blocks

I’ve tried adding a Headline block and opened dynamic data, set to:
data Source: This post
Content Source: Meta data

But can’t find any of the custom fields I’ve set up to appear on all Projects post types.

I’ve tried playing around with the above settings, but no joy.

Pretty sure I’m doing something wrong, but any help would be hugely appreciated.

Thanks

Luke
