I fail to understand your response, @lubos. This is clearly a bug, yet you did not mark it as such when you edited the title to remove capitalization. The other topic you linked you removed from the bugs category, but nothing was fixed.
The problem is clear: the default Special Accounts control account name (or whatever it might have been renamed) is showing instead of the custom control account to which the special accounts are assigned. But account postings are correct. And View screens (for journal entries) show the correct custom control account designated for the special account. So this is just a labeling problem on Edit screens. Based on content of my companies, I can determine that this problem description applies to journal entries and receipts, but I had no pre-existing transactions of other types.
I do not understand this statement, either. If you edit a transaction showing the incorrect control account by selecting the correct, custom control account, the edit is saved. That is, it is permanently changed.
