Attendance (plugin)

Hello everybody,

I'm new of this forum... I found this moodle long time ago, but I never use it... so maybe some one allready fixed it.

I'm using moodle 1.8.7 with attandance, and sometime, into the attendance tab, the green icon in the action column cann't disappears when I set the lesson.... This is a big problem because the students cann't see the lesson on their report.
It seems without a sense: no about specific course or date... this happends random in my moodle... I don't know why...
Some body can help me?

Thanks
Davide
