The item-count in Lists is off

I noticed this issue at the beginning of the year already (and reported it), but apparently it’s still present.

As you can see I have several lists, the one named Test apparently containing 6 items (Item 1, Item 2, Item 3, and 3 more)

However… That list doesn’t contain 6 items. It contains only 5!

Cozi customer support says they’re unable to replicate the issue, and that no one else has reported it. Therefore I’m taking the issue ‘to the streets’ and am hereby asking everyone: Am I truly the only user of Cozi experiencing this miscount, or am I simply the only person who has reported it (thus far)?

(I’m showing it here in Shopping lists, but the same issue occurs in the To Do section)

Hey you back from the Welfare office
