This happens every time in my campaigns when there is a new update to the sheet. Duplicates of the existing armour are added, and worse. What appears to happen is that the update process looks at the items that are showing in the Armour Details section . It then duplicates them in the Equipment section Armor Tab - leaving the Magical checkbox unchecked when the items were originally marked as Magical - and then makes the new duplicates the items that are showing in the Armour Details section . This appears to happen 3 times. The following are screen shots of a character in one of my campaigns. Last week, I updated these characters and made sure the Armour Details section matched the Equipment section Armor Tab. I have done the same in another campaign and the same thing happened. 1. Here we see the Armour Details section . All looks fine. The three bits of armour this 11th level thief has are all magic and are AC 8 bracers, +2 Cloak, and a +1 ring. 2. However, slide down to the Equipment section and look at the duplicates! You can tell the 3 items I entered last week because the Magical checkboxes are ticked. The AC 8 bracers, +2 Cloak, and a +1 ring are repeated 3 times! You'll also notice the duplicates do not have the Magical checkbox ticked. 3. So what do we do? Let's delete the last three first. Here you see the Equipment section , Armor tab has 2 of the duplicated AC 8 bracers, +2 Cloak, and a +1 ring left after deleting the last occurrence of these three items. 4. Now we expect that since the Armor section will be the same as it was in 1, above. Unfortunately, it is not. The sheet update process has done as I described initially: Duplicates AC 8 bracers, +2 Cloak, and a +1 ring in the Equipment section Armor Tab and then makes the new duplicates the items that are showing in the Armour section . However, when deleting the last set of duplicates, the entries of AC 8 bracers, +2 Cloak, and a +1 ring in the Armour section have disappeared! Again, this has happened in both campaigns. Mysterious duplicating armour items have been happening a lot, at least since I started two new campaigns in October, and I am positive it was a vexing issue before that.
