Library/Uploaded to post not working (shows entire media library)

Hi!
Someone asked for something similar a week ago, but I think this question will be clearer.

In an ACF (backend) gallery or image field, when you select this option, only the images uploaded to that specific post are visible when editing the field.
However, in Frontend (this plugin), all the images uploaded to every post are visible.

This is crucial for sites like mine, which allow users to rearrange, select a featured image, etc.

Is there any workaround to this issue?

Thanks in advance!
