This is one of those odd situations that occur. This sentence was deleted months ago but continues to reappear from time to time. Where did you have this sentence: on a test out section, multiple choice, strengthen skills etc?
Thank you for the report as you will see from previous posts we have been trying to have this corrected. This is not dependent on the team but on the Duo server. We have reported it and hope it will be corrected soon.
sorry for the delay in answering. It appeared on a test out! Thanks for your reply..
It's still incorrectly saying that ένα κιλό is wrong. This is on general strengthening skills.
