Translation:We saw shadows on the ground and we were scared.
Only in Munster Irish. In the Caighdeán and in Connacht, you don't eclipse d and t (and in Ulster they lenite).
The exception for d and t (after certain prepositions and an)is mentioned in the Tips & Notes for the Eclipsis skill
An exception to this rule is that the word should not be eclipsed if it begins with d or t.
(Duolingo teaches the Caighdeán rules, but is usually fairly liberal about accepting dialect variations).
"Duolingo" doesn't read comments on sentence suggestions - the only people who will see this are other learners just like you.
If you want to tell Duolingo about a problem that you are having using the website or one of the various Duolingo apps, take a screenshot that demonstrates the problem, and submit a bug report with the screenshot and a detailed description of the version of Duolingo that you are using (iphone app, android app, website, the web browser you use, etc).
