Papyrus not generating in savanna shores and jungle biomes on v7 map generator

[Priestessofspiders]

Running Luanti version 5.10.0, latest version of minetest game.

Have checked savanna shore biomes and jungle biomes for several hours in search of naturally generating papyrus, searched for several thousand blocks in multiple directions, have been unable to locate any. Problem exists in the v7 map generator, multiple different seeds have been tested.

Also noticed this. It seems that the water-level is one unit too high (or the shoreline is one unit too low). You can observe it by flying into newly generated areas and see that grass is just under the waterlevel and slowly turning to dirt.
