Albon had started fourth and tumbled down the order as one of only five drivers to commit to slicks, opting not to make a late change to intermediates.
He subsequently climbed back up the order and was running as high as sixth when the rain returned in the closing stages.
Vowles conceded that staying out at the start ultimately turned out to be the wrong call.
"You either stop on lap one or lap two, or you stay out," Vowles told Autosport.
"And the real wrong that a number of teams did is then stop after that point. Once you're committed, commit.
"The reason why we didn't stop was on the radar initially it didn't look like it was going to be as bad as it was. Now, clearly, the losses were quite significant to inter runners.
"You still saw us come back into a points position. It's not outlandishly terrible, but it was the wrong decision."
Albon again initially stayed out on the lap when most of the field came in when the rain hit the track late in the race, stopping instead on the next tour.
Vowles said the second strategy call was also the wrong one.
"What we need to go back and do is go look at our systems, our tools, our communication, what can we improve in that process? Because we got it wrong," he added.
