drop, pick, containerItem doesn't work properly

[Nikita Kalinin]

I have a block with a few metatypes:

name = 'myblock';
...
// Metatype 0
drop[0] = 'mymod:myblock:1 1';
pick[0] = 'mymod:myblock:1';
...
// Metatype 1
addtoCreative[1] = true;
...

When destroying a block dropped block have same metatype that it has in the world. When it's picked happens the same. Also tried: 'NAME:1', alias 'myblock'.

I need to make an item that can be used unlimited times in crafts. This item should stay in crafting grid.

name = 'myitem';
...
containerItem = 'mymod:myitem';
leaveContainerItem = true;
...

It disappears after craft. Also tried with aliases.
