Assuming H2N exports the hands in the site's native format it could be a bug in the 2+2 converter. There is
a dedicated converter thread here.
Paste the hand here or in that thread using the CODE tags and let us know what site the hand history is from. If you don't want to post the hand publicly you can paste it into a txt file then zip/attach it to a support ticket with a link to this thread and your forum name.
Please
create a support ticket via the Contact Support link and if there is a forum thread with additional information please link to this thread and let us know your forum name if there are several people in the thread.
