1) Im already running 7.1.1, so why does it say its upgrade from 6.8?

2) I found this bug that is related to the get_value error:,
but it doesnt appear to apply to mine as you can see above, im getting the right result there.

Here is line 3416 on the file:

    my @attrvals=$entry->get_value("olcDbIndex");
Any ideas?
