I noticed the same thing with my (pre-packaged) amazon swords that were apparently grown out of water. In my case, once planted new leaves began to grow, more narrow like yours, while the older outer leaves slowly turned brown, I eventually trimmed these off. In your case, as long as they remain green and healthy, I would leave them be.
For my (again pre-packaged) water wisteria, the leaves were very broadleaf...but the new growth was feathery. Another sign of a plant grown immersed rather than submerged. As the plants grew larger, I cut off the broadleaf base (discarded) and replanted the feathery stems (which now have rooted and are growing very well.
