This issue is mentioned in the manual as one of the limitations of the infinite scroll plugin, which I introduced into Ikebana in version 3.0 following user requests. However, I did find a solution and will include it into version 3.1 of the theme, which is due to be released next week. Meanwhile, I’ve sent the 3.1 build of Ikabana to the email you’ve provided when registering on this forum – please download the archive, unzip it, and upload into the theme folder (i.e. /wp-content/themes/) inside your WP installation. Please let me know if it helps!
