Blast furnace not craftable

[AstroKiste]

Having all the materials the blast furnace cannot be crafted because the needed furnace is red although it is in the inventory.
Placing rhe furnace by hand into the center slot leads to no output.

This is the android client as well as the ios client.

I can verify this. For both blast furnace and smoker, the crafting table will not accept the furnace.
