Hello @chanm
Thank you for reaching out to the Community regarding your issue, although I am sorry to hear that you are experiencing issues with your reconcile window. One thing that might help us here in figuring out the issue would be to get a couple of screenshots of the issue as that'll help us figure out what might be happening. I'll leave an article down below on how to do so.
