In Projet Issue View, all provided links are based on generic concept and predefined filters (in system-preset-filters-sections.xml), and their translation causes

All these filters refer about list of issues following different filters, and may return between 0 to n issues.
In French, "Issue" is translated "Demande" which is feminine name, and adjectives have to agree in gender and number.

Then for all i18n key work based on an adjective, English has no need to make a difference between singular and plural, but not in French. I will not try to explain in English special rule related the usage of verb "Avoir" (to have) and "Etre" (To be), but it has also an impact on how we write adjectives.

By exemple, i18n key like "common.filters.<adjective>" should be translated with plural and feminine

common.filters.addedrecently=Ajout\u00E9es r\u00E9cemment
common.filters.updatedrecently=Mises \u00E0 jour r\u00E9cemment
common.filters.assignedtome=Qui me sont attribu\u00E9es

common.filters.reportedbyme=Que j''ai rapport\u00E9s
common.filters.unscheduled=Non planifi\u00E9es

Some other is correclty translated :

common.filters.resolvedrecently=R\u00E9solues r\u00E9cemment

And "common.filters.outstanding" has been translated "Unresolved" like "common.concepts.unresolved", but due to the associated filters, where only the order differs, we shoud have a better translation ...

The term "outstanding" has many possible French translation in google (https://translate.google.com/#auto/fr/outstanding), but none of them express the order on Update Date.
And same remark for the translation of "common.concepts.unresolved" ... the order of the filter is not visible in the translation.

What is sure, is that these both translation should not be the same.

My proposal would be

common.filters.outstanding=Non r\u00E9solues et mises \u00E0 jour r\u00E9cemment
common.concepts.unresolved=Non r\u00E9solues par priorit00E9s

Except these 2 last key words,the other corrections have been also proposed in https://translations.atlassian.com .
