Crimson lotus flower / Sickle

I’m not sure if it as intended but my acheronian sickle just tore through the plants with no yield. Hand picking them gave one crimson lotus flower per plant.

Same but with 2 flowers per handpick in the dead mound lake or whatever.
Sickle not works on them at all on official serve PVE#2 fast on PC.
also can’t aquire any seeds from them I mean not a single seed were taken after clearing the area of them (by hand).

I have the same issue with Red Lotus and the sickle, although the sickle seems to work on all of the other lotus flowers.
