Execute Command Does Not Work In 1.12-pre2

So I'm currently working on a command that will summon villagers next to an armor stand. Whenever I updated to 1.12-Pre2 I found that the command blocks were ignoring the /execute command and just summoning on top of the command block.

Example command: /execute @e[type=Armor_Stand,name=SellCropsVillager] ~ ~ ~ summon villager ~ ~1 ~

There is more to this command but I just gave you the part that isn't working.

Full Command: /execute @e[type=Armor_Stand,name=SellCropsVillager] ~ ~ ~ summon villager ~ ~1 ~ {CustomName:"SellCrops",Profession:5,Willing:1,Offers:{Recipes:[{rewardExp:1b,maxUses:2147483647,uses:0,buy:{id:wheat,Count:32b},sell:{id:emerald,Count:1b}},{rewardExp:1b,maxUses:2147483647,uses:0,buy:{id:potato,Count:20b},sell:{id:emerald,Count:1b}},{rewardExp:1b,maxUses:2147483647,uses:0,buy:{id:poisonous_potato,Count:6b},sell:{id:emerald,Count:1b}},{rewardExp:1b,maxUses:2147483647,uses:0,buy:{id:carrot,Count:18b},sell:{id:emerald,Count:1b}},{rewardExp:1b,maxUses:2147483647,uses:0,buy:{id:beetroot,Count:14b},sell:{id:emerald,Count:1b}},{rewardExp:1b,maxUses:2147483647,uses:0,buy:{id:reeds,Count:32b},sell:{id:emerald,Count:1b}},{rewardExp:1b,maxUses:2147483647,uses:0,buy:{id:cactus,Count:28b},sell:{id:emerald,Count:1b}},{rewardExp:1b,maxUses:2147483647,uses:0,buy:{id:dye,Damage:3,Count:8b},sell:{id:emerald,Count:1b}}]},ArmorItems:[{},{},{},{id:emerald,Count:1b}],ArmorDropChances:[0.085F,0.085F,0.085F,0.0F],PersistenceRequired:1,Silent:1}
