The swords are looking good now, so that is resolved.
As for the floating plants, the photo shows Frogbit. I have the same issue with mine, which I had thought was because I have the temperate species, not the tropical, and I know this because mine flowered once and the flowers of the three species are different. You may have the temperate species too. Or this may be just getting settled; mine took a few weeks. I have had good growth in a couple tanks (I tried it in several when it was failing) but the leaves do yellow as yours are doing. Give it a few weeks before giving up.
