Different Reports on Same Training

We are still running an older version of Breeze and have over 1300 learners on our system with about 500 training courses. As such we have a help desk for our users (the biggest bulk of them all belonging to our own company) and we experience this all the time ie training completed not moving to the completed section.
We also have an issue where when a user logs in from their home PC they see a courses which they completed months ago but when they log in on the company network (still looking at the breeze server) they see a different set of courses.
If anyone has any comments, I would be very interested to hear from you.

James, thanks for the extra info. I've done a bit of digging and it looks like Breeze (Connect) records the LAST action taken by a visitor, so if for example, a visitor passes a particular training, and then re-opens the training for a partial/incomplete view, the training report will register an incomplete, while the visitors' report will show a completion/pass.

There may also be a setting in the Quiz Settings while in PowerPoint that may alter this behavior, but this will take some experimenting. I'll try to post any new findings here, but still open to others' suggestions.

I've not seen that before. I've seen similar things, but only when currculums were involved and users were enrolled in mixed ways (ie. some enrolled in curriculum and some in the course). In any case, your only recourse may be the usual 'enter the completions manually'.
