I just installed a local Moodle 3.10 (Build: 20201109) with the mexican Spanish language pack.
But when I installed the StudentQuiz plugin (version available for Moodle 3.10), some strings are not translated (e.g. 'Delete orphaned questions').
Might this perhaps be related to the fact that Amos has versions for Moodle 2.0 to 3.9, but no 3.10 version ?
