I decided since I wont be on for a bit to boost my que'd troops I que'd days ago.  I went along each Que and boosted them using several 10 min, 15 min, 30 min and 1 hr Boosts totaling about 24 hrs.  It showed the que's empty.  I went to acropolis to put them away and when I scrolled bar across all of them then send, a message came up saying to select another number to purchase??   I tried a few more times then refreshed the game.  When it reloaded, all the que'd troops were back in the que's but the boosts were used.  Not sure if this is a bug but I just lost a load of boosts I was counting on and earned.  I would appreciate this looked into.
