eab_archive still showing i'm attending buttons for public announcements

I am using the eab_archive shortcode to display my upcoming events:
[eab_archive lookahead="true" weeks="52"]

However, I have marked all these events as public announcement events but the 'I'm attending' buttons still display for these events:

Is there any way to remove these buttons?

Thanks,

Conor
