Hello, I created a key with kleopatra on Windows and the trust level was ultimate with a green checkmark. Someone else signed the key and sent it back to me. After importing both keys (the other persons public key aswell as the signed key) it shows as signed to all identites but the trust level is now unknown with a purple question mark. If I try to set the level higher back to ultimate the verify (German "Beglaubigen") Button cannot be clicked and is deactivated. AS this is my personal Key I do not quite understand why the trust level is unknown. If I delete it and import it again without the signature the trust level is again ultimate. How can I solve this issue? Kindly
