Lana was already established at a character through the games, so she was already popular.
Dot is exclusive to the anime, which not that many people watch, at least not compared to the amount of people who play the game. She's not that popular yet.
There's also a few other factors, such as the fact that Lana is a bit more appealing to lolicons since Dot's design is a bit more tomboyish. Also, Lana's mom is literally just a more mature looking version of Lana. If Dot's mom looked like an adult Dot, I think she also would've been a bit more popular.
