Can't save custom camera views


I have my Save Custom Views mapped to Right CTRL + Num x and in they all detect and save fine in the Control Options. However when I setup a view in an aircraft (used Fenix for this example) and hit my key mapping to save, nothing happens. Other camera views as specified in cameras.cfg work fine but the new one is not saved.

I have tried the suggestions to ensure that global option camera Heigh/zoom are set to 50 and ensure that there are no other key bindings.
