Utrecht is one of the strong teams in the Eredivisie, mate. So I think it's normal if they can draw against Feyenoord, especially since their match took place in Galgenwaard. For the Groningen Vs Feyenoord match, the handicap bet is also at -1.5 if you choose Feyenoord and want to get at least X2.
Feyenoord won't lose later, their worst scenario is that they win with a score of Groningen 0 - 1 Feyenoord. Too bad, mate. Even if it's small money, you should just save it for more potential bets, but, i only can say "good luck".
