Translation:Your question does not have an answer.
Unfortunately, on the very first stages of building the tree, the rule wasn't taken into consideration by the original creators for all sentences. Some double accents are missing and can't be edited in, in main sentences (at least not now that the tree is released). However, we do include the double accent alternatives, so that they are marked correct. We apologize for the inconvenience
How can a question HAVE or not have an answer? Does it mean, that: There IS NO answer for your question? ((In German: Es gibt keine Antwort auf deine Frage.) Or maybe: It doesn't exist an answer for/to your question. ? There is only a whole translation of the sentence in the hints on android. This makes is impossible for me to understand, what the greek words and the whole sentence mean. An explanation would be fine :-)
