Hi
I am having the same problem — actual remaining stock is 2 plus 3 tickets awaiting payment, total number of tickets is 40. Woocommerce shows it all correct. Event Tickets shows “sold 35 of 62” — 35 is correct number of completed orders, not counting 3 not paid, but why the hell total is 62?
When I am trying to edit the ticket, it shows Stock as -11. I tried to change to 2 — just no effect, it remains -11. I tried to get around this and changed to -20 (if it shows additional 22 tickets in stock then I will try to decrease to see 2) — it showed me 35 out of 40 remaining in admin area and Out of stock on event page. And in ticket options stock became -34 :).
Here is a screenshot http://www.screencast.com/t/m9c6TIVJ
And on event page form shows 24 out of 62 available but Woocommerce does not allow to choose more than 2 tickets.
