I don't think there is anything to worry about, it looks like old mechanical damage, that's already healed up a bit. As for the pic of the leaf that has a line going down the center, sometimes that happens to phals, I'm not sure why.
The leaves are just going to look ugly for a long time until the plant grows and naturally loses those leaves.
