Axure Share bug in push/pull of widgets?

I created a list of items. One of the items has a set of nested options. When the dropdown is triggered, one of the items below disappears on the Axure Share version. It doesn’t disappear on my local version.

Like this:
Item 1
Item 2
Item 3 (this toggles a nested list - open by default)
– nested item
– nested item
– nested item
Item 4
Item 5
Item 6 (this item disappears when the dropdown is triggered closed, and does not reappear
Item 7

Fixed. I deleted the disappearing item and created another. The structure was identical in all the list items. Gremlins.
