Hey guys,
Sorry to revive an old thread but I found it searching for a way to retrieve the target and title of an ACF Link field to use in Bricks with dynamic data.
I see a fix was implemented but I donāt see how to use it 
For anyone else who finds this in future: you must use the array_value filter - docs examples here.
You can then use {acf_your_link:array_value|title} in the Bricks editorās āAttribute: titleā field, which accepts dynamic data.
You need to create a target attribute yourself from the Style tab, then set that with {acf_your_link:array_value|target}
IMO Bricks team could add the target attribute as one of the direct dynamic data inputs, alongside rel, aria-label and title. It is the only one missing that is natively passed in the array from ACF Link field.
