Am i blind or what?
Seriously i tried to find a mistake in my sentence but i couldn't

I honestly can't say why, but Duolingo seems to have some sort of bug that occasionally marks correct answers as incorrect. When users report them, they're already listed as correct on our side, too. It's a totally baffling bug, and I wish I had some idea why this happens, because I know how frustrating it must be to have correct answers marked incorrect for no apparent reason.
No. Listening exercises currently can't be programmed to accept multiple answers, and Duolingo's programming wasn't made for a language that has multiple writing systems like Japanese, in which you can transcribe the same sentence in multiple ways (using all kana, using kanji for words that have them, or using a mixture of both). As far as I have heard, Duolingo's actual staff is aware of the problem an looking into it, but I personally have no insight into their programming or process on trying to resolve it.
Use image links that have .png, .jpg, .gif, etc. in their URL. You cannot use images from your computer, you'll need a link to an image that is stored up on the WWW.

This error usually pops up whenever Duolingo puts spaces between words where they aren't supposed to be sometimes when a word gets placed. Usually when this happens, I just drag the word and place it onto the space to fix it. It's a really weird issue. This also results in word duplication, which has happened to me before.
