Is there something wrong here?

Did a Commerical floor clean for this LVP and the side the pictures are from show what appear to be like wrinkles. What is strange is the same tiles down the in the offices are flat. This hallway gets heavier traffic with folks coming in from an industrial like warehouse. I'm baffled as to what would cause this or explain why this side is not smooth like the other areas with the same tile. Office manager said it never used to look like this and thought a good cleaning would make it look better. Tried a neutral cleaner then an all purpose cleaner specific for the floor along with a floor machine and a sqaure scrub. Am I looking at an issue with the tile or is this the way it was manufactured? I'm at a loss. We have cleaned it twice, with second time using the APC as it does better at breaking up oils and grease. I think we got the same outcome.
