The useage of the campfire block, scaffolding block, fletching table, blast furnace, and smithing table is problematic.

Several new blocks in the new snapshot dont allow me to access them or use them properly. I understand this is a beta verson but I  would like to put this to your awarness as im a concerned user. The useage of the campfire block, scaffolding block, fletching table, blast furnace, and smithing table is problematic. 

• Campfire block does allow the >4 food placement but not the nether star is unable to be placed to create a smoke signal. (images below)
• The Scaffolding Block when placed on top of the another one is placed in front instead. To place a block on top of one another you have to click the side of the block where the scaffolding is present. (images below)
• The Fletching table does not allow any sort of function to occur (when right clicked on, nothing happens).
• The Blast furnace does not allow any action to occur when in the state of placing a fuel to influence an outcome upon an object (image below). In other words, nothing happens if I place the items I researched that can be used in that block.
