Trial Balance - Detail Assets

Hi,

Version 11.5.10.2.

I've an issue where a nominal (account) was setup originally as an Asset expense type. Transactions were made against this as an Asset and the expense type should have been Expense. I've tried to correct this by...

Backing the original transaction out as an Asset

Amending the expense type on the nominal from Asset to Expense

Restating the invoice with expense type as Expense

When viewing the transaction in payables I can see a 'Track As Asset' flag was ticked on the original invoice and reversal, and after amending the expense type this is not ticked. (is this even relevent?)
