You ay that you are getting ‘false’ as a result from get_field. Isn’t this because you haven’t saved any data due to your first issue?
I think we should ignore this get_field issue for now in light of this.
As for the slug issue. I have tracked down and found the source of the issue.
The problem is a piece of code which provides compatibility from older versions of ACF data.
I think this can now be removed as it is obviously causing a major issue. I’ll remove the code and push the fix to github.
Can you download the latest code from github and test?
