strange interactive book reporting

Hi all!

I found a strange reporting behaviour in the interactive book activity:

- content created with version 1.11.11 reports every xapi statements into moodle, so one attempt are represented with 8-11 lines in the activity screen

- content created with version 1.7.12 reports one attempt as on line

How can I achive that 1.11.11 would behave like 1.7.12? I have several interactive books, and my student reporing is now broken becasue of the different behaviour.

I' not sure is this a bug or some general setup I can change so sorry if is this a wrong topic.

thanks
