Custom blocks don't work.

Every time I load-in an Addon with custom blocks, some of the block components are not valid. For example if the blocks code !only! contains minecraft:friction and/or minecraft:absorption values, everything works.

If the block contains for example minecraft:entity_collision, the in-game log gives out errors (errors included in the picture).

Even tho the values are from a normal block ( "origin": [-8,0,-8] and "size": [16,16,16] ).
