Drops from custom blocks not working and custom blocks texture wrong

texture wrong :I made a custom block (ore), in my inventory it have the good texture but when I place it on the ground it take the mushroom texture.( and it will take double consumption).

drop wrong : i make a custom block when break it and nothing drop , im sure my yml is correct.either custom block's "required-power" is higher than pickaxe or lower, i always could break block and nothing happend,may be "required-power" and "require-power-to-break" is not working?

another question: i use itemadress plugin to replace mmo ore texture,but it use ia plugin's drop table instead of mmo drop table when break block, it's correct result ?(is right texture when a place it on the ground) mmo version : 6.9.2
