Norwegian fjord ferry miscalculated

Ferry from Vennesund to Holm. I put in manually the correct time for departure 08.10 and arrival 08.30 then pressed the calculation button. The result (“Drive”) is

shown on the screenshot. ABRP insisted on changing the arrival time at Holm incorrectly, and the harbours appear several times on the route now. Wrong times and extra kilometres, as if ABRP wants me to go back and forth several times? I pressed the Bug button ca. 23.00 CET
