Depreciation process generates different reserve accounts

When we run our depreciation, we have identified a number of assets, that belong to the same category and have the same expense account and location assignments, that have different or no depreciation reserve account associated with the depreciation.

For our depreciation reserve account, which is a category level account, our account generator workflow selects our balancing segment from the distribution (expense) account, and all other segments from the category for the asset.

For some reason the cost centre for some of the assets appears to be being selected from the account generator default for the book, while others are selected from accumulated depreciation account for the asset category.
