Why did Adela have the least amount of fan voting in DA?

I wasn't around when the survival show was happening in real time, I only got to know Katseye after they debuted and I watched the documentary recently.

So I don't know what were the general opinions and reactions to the girls on the internet at the time of DA.

But it baffles me that Adela was ranked the lowest in fan voting, how did that happen? She obviously has the visuals, the vocals and the dancing, so what did fans not like about her?

For the people who were following the voting and online commentary on DA at the time, what were the general opinions about her on the internet? Why do you think she had the least amount of fan voting?
