Disappearing azolla and duckweed

I introduced a small number of azolla and duckweed in my fluval spec 5 and a 1.5 gallon jar. I only 2-3 clusters of them at a time because Iím afraid they will multiply and get out of control. They all slowly disappeared and I put in a couple of them more and theyíre gone again. From time to time, I saw the snails grazing underneath them.

The jar has nothing but exhausted active soil, a floating branch of anubius petite and some pond snails and the tiny ramhorn-lookalike ones (they are not ramhorn but I donít known the name).

The tank doesnít have much stocking at the moment after I was away for 3 weeks and asking my friend to feed the tank.. and well, I lost several shrimps and the snails population also in decline.

I suspect the snails ate them. And if so, does it mean that they donít have enough biofilm so they snacking on the azolla and duckweed? thank you. @novv

Before we can even begin to figure anything out, we need to know the water parameters.

Snails might be "clockwork" snails? I haven't seen them, google images doesn't show an actual snail... but they are similar in appearance to ramshorn, supposedly.
