Litespeed metabox appear on ACF field group edit pages

Hi

The Litespeed metabox should not appear non post types that are set to “private”.
More specifically, the metabox appears at the very top when you use the Advanced Custom Fields plugin to edit their Field Groups (because they don’t have a sidebar).

Steps to reproduce:
1) Install the Advanced Custom Fields plugin v6.0 or newer
2) Go to Custom Fields and create a new field group

Result: The “Litespeed Options” metabox appears on the edit screen, followed by the ACF Field metabox (in ACF 5 the Litespeed metabox appeared in the sidebar which is still not ideal, but less intrusive).

Expected result: The “acf-field-group” custom post type definition has “public” set to “false”, so Litespeed should not display a metabox on this custom post type’s edit screens.

I hope you’ll consider fixing this. Let me know if you need more information.

Thanks in advance
