Security Question: Creating Custom Role "Adjust Asset" is unavailable under "Transactions"

Summary:

When I take the out of the box "Asset Accountant" role (ORA_FA_ASSET_ACCOUNTANT_JOB) and apply it to a user it has the "Adjust asset" ability under "Transactions" on the task menu. The only step that I've taken is to copy the role, and without changing anything from the user, the "Adjust asset" is no longer showing. I'm not sure why this is the case. I need to create a custom role that allows the user to have access to "Adjust assets" but each role I copy loses this ability and I'm not sure why it's doing that.
