I apologize in advance if this is already well known or being fixed, but I’m posting anyway because it’s the weekend and I’ve got important things to put off until the last minute.
Numerous choices have icons below them that inform you about what conditions must be met before that choice is available. However, the interface does not make it clear about what consequences will result from that choice, regarding those prerequisites. For example, at the London Drydocks, there are numerous options for ship repair, "Unlocked with X echoes (you have Y)". If you have that much and select that choice, that amount is deducted from your funds. That is fairly easy to understand.
The problem, in this case, is with the Admiralty Yards option. Looking at the requirements, "Unlocked with 5 Admiralty’s Favour (you have #)" the player would understand that choosing this option will take away 5 of their Favour and the required echoes. Yet, this does not happen, as seen in these screenshots:

Other instances of requirement-to-cost disconnect exist: The option to "Speak to a Higher Authority" in the Admiralty has a prerequisite that does not cost anything.
