If it helps, I've heard in other discussions that plurals can almost be considered their own gender when it comes to many nominative pronouns. Often plurals follow the feminine nouns for deciding what ending to use for possessive pronouns, at least as far as I know.
"Dein" means "your", and works for Masculine and Neuter nouns "Deine" also means "your", and works for Feminine AND plural nouns.
Other possessive pronouns like "Mein/Meine", "Euer/Euere", "Unser/Unsere", and "Ihr/Ihre" work the same way.
Eltern itself is weird to me because it's the first word I've seen in this language that is always plural. So far I have been using feminine pronoun forms for Eltern and things seem to be working okay. I hope this helped!
eat - ear -- now, that's a clear typo... This is a bug. If the typo makes a regular word, it's considered as wrong translation, and I guess it's not checked if it can be a possible typo. It's frustrating, and extra frustrating when learning on a smartphone where typos are very frequent.
I guess this is not the place where I should report this problem, but not knowing where, I decided to report it here. Please move it where appropriate. Thank you.
