This happens to me as well with multiple clients. The transaction is marked reconciled, and is not a duplicate yet it shows up as an uncleared transaction.  I tried unmatching, and re-categorizing from the dashboard, then marking reconciled in the register but it still shows up on the Uncleared Transaction list. This is very frustrating, and I just ignore that list because it is not accurate.  I wish a solution other than "call support" would be posted here ...
