Isn't that how Democracy works? If there is lets say 4 candidates for president, two gets 20%, thrid 25% and fourth 35%, then if there is only one vote, that guy with 35% gets to be choosed, despite 65% people voting something else.
The problem could be quickly solved with another vote if one map doesn't get 50% or more votes, or "priority" vote where you choose priority of each available map, so if your higher pick has no chance of winning, the vote is not wasted as it goes to the lower priority.
However that would be only "jury rigged quick fix", because people vote LV and Big Red for reasons. Benos also vote ICE for reasons. First two are fairly balanced, thrid is biased for the one side.
