We tested using filters in the Ledger and applied them. We did not like the filter results, so we deleted that filter. However, the filter did not re-set itself (i.e, when we viewed accounts, that filter was still active, accounts showing red, even though the filter had been deleted). To solve this "problem" we re-created that filter as best we could, applied it, and reviewed the results. Once we were happy that the filter again worked, we re-set the colour back to the standard, which in effect re-set the account colours back to the original colours. At this point, we can probably delete that filter again and all would be well. Is this the proper way of deleting filters we no longer need?
