Only the first floor of each deck property type pushes successfully, with all others not recognizing their deck property

#### Description:
As per the title, when pushing multiple floors of the same type (eg all "200 THK") only the first goes through. The rest have their slab edges drawn in RAM, but the Deck is not assigned.

#### Steps to reproduce:
Push multiple floors with the same Property applied.

#### Expected behaviour:
All floors push with Deck types appropriately assigned.
