Some items are not transferred properly when converting a Legacy PS4 world to Bedrock

When transferring my world from Legacy Minecraft: PS4 Edition ("Editions") to Bedrock, I am losing all building blocks from my inventory and chests. This also includes other placeable objects that may not be considered proper blocks (such as Torches, Saplings, Flowers, Scaffolds, and Shulker Boxes). I have transferred my world several times with the same outcome. This issue is preventing me from comfortably migrating my world to the Bedrock edition of the game.
