Fixed issue that mainly effects capture histories where fish is released above a dam but the dam is not included in the capture history. When multiple detections occur at a site the program was not properly combining them, resulting in the last detection at any site being used. But when one of these sites was downstream of the release but upstream of the first capture history site this would result in large numbers of fish being removed before first capture history site. This error only occurs in the Removal-Trumps-All mode with Allow single coil detections checked.
