Is this bad

[PaphMadMan]

The corrugated appearance of the leaf in the first pic is perfectly normal for many hybrid Maudiae-types. Nothing to worry about at all in terms of plant health. It seems to happen most often in plants with thick heavy rigid leaves, possibly a side-effect of breeding for robust plants and certain aspects of flower quality, or in tetraploid plants.

The second pic with the brown/yellow edge where the leaf was cut doesn't look like anything to worrry about either, unless it is spreading rapidly. Especially if it is an older leaf I wouldn't worry about it. A picture of the whole plant could help determine if is anything more serious.

My overall impression from the pics is that it is a healthy plant. My only advice would be that if it hasn't been repotted in the last year it is over-due.
