Sorry Mike I have found a bug, I posted this in the Troubleshooting section earlier, but have moved here in light of more recent investigation.
I have noticed a rather odd behaviour, which doesn't seem to cause any problems, but is probably worth noting.
When creating a rucksack of taxa (using the rucksack generator), if I add a taxon for which I have previously added a common name (via Edit Taxon Details), for example genus level taxa such as Carex, which I have named 'A sedge", the item appears twice in the rucksack window. The same thing does not happen with genus-level taxa which I have not edited. I initially tried deleting one of the duplicates, but next time I opened the rucksack it had returned. I think if I delete both entries it stays deleted.
Clearly this is only an issue of what is actually displayed, since the rucksack cannot actually contain multiple copies of one TLIK (or maybe not?)
OK that was what i thought a while ago, but since then I have been adding a few items to the rucksacks I created with the tool and it would appear that when a rucksack is saved, the duplication becomes real.
That is to say that it becomes impossible to open the rucksack again. A dialog appears suggesting that the rucksack may have been deleted (which it has not). Opening the rucksack file in excel reveals that there are duplicate TLIKs there and that the taxa affected are only those for which I have added common names.
So it would seem there are two bugs here. One creates the duplication (I cannot tell if it is the tool or the rucksack window doing this) and another which allows the rucksack to be saved without checking for duplicate keys
