Good afternoon Plarium ,
The same thing is happening to me. The past 2 days I've received the Mar'eth Quest "Train 7 Units (Necromancer, Imperial Necromancer)." Both days I pushed 7 Necros out of my training queue, and both days I got credit for 0 of them. Today I completed all of my other Daily Mar'eth Quests, so this is preventing me from claiming my bonus item (an Iron production boost). This is also negatively impacting my Weekly Mar'eth Quest "Complete 25 Daily Mar'eth Quests." and my Monthly Mar'eth Quest "Complete 100 Daily Mar'eth Quests."
Latest batch of 7 Necros are gone from my training queue:
...but no credit for any of them, again:
