I couldn't really report this with the picture and word pair - it asked me to pick the picture for the word FOURTY instead of forty. Common misspelling needs to be corrected.
Yáʼátʼééh! In that case, please report the picture so that the contributors will receive a message on the incubator board. Or else, just take a snapshot and send it in a bug report.
I hope it helps. :)

I did report it, as picture not matching word which was the only choice. There is no discussion on picture match exercises, unfortunately. Hopefully, someone will catch and correct with what I did report.
