Red Warning for FX Rate Update for manually added exchange rates

Let’s say one changes USD to EUR at a money changer and then adds this transaction to kMyMoney. He will use the FX rate he got at the exchanger, and not the online rate. So far so good (despite adding a custom rate requires to read and find a post on kmm on how to do that).

Kmm then adds this custom rate as an entry in the list of Online updates, i.e. kmm will search for this day’s rate online, and create a red entry (does not seem to be a failure as failures throw a dialog box up besides the red text) in the update dialogue log - see screenshot.

Why the red message? Its wrong here, as there is all fine with the custom rate, so no red message should come.

Besides that - why is there an FX entry in the update list at all for such manual entered rates?

Is there a way to customize which items shall be updated or not? I have some years old transactions in Rupees or other “holiday” expenses which are stable and have a proper rate assigned. Why is then the update dialogue years later still trying to get rates for this unused currency?
