I'm in the process of entering information for payload mass (P4519). Currently, I copy paste the information in the form of "13,150 kg". When I paste it into the statement I can't immediately click save. First I have to remove the kg. Then I have to click on the field for the unit. After writing kg I have to select the second choice (the system things Kazakhstan could be my first choice for a unit).
This process is needlessly complex given that kg (kilogram) is already set as preferred "used for this property (P2237)".
