Hi there I’m brand new in the WordPress…

Hi there,
I’m brand new in the WordPress translation world and have just started tipping my toes on the WordPress Android Catalan translation.
I have noticed, though, that someone else had proposed some translations last October which haven´t been validated yet.
Is it normal for translations to take so long to be validated? If so, please forgive my over-eagerness.
If not, is there any way in which I could assist?
Many thanks in advance.
