I was making a big storage system in creative and i was testing it then i found
out that the hoppers were not behaving normally. I tested how the hopper reacted at normal chest, it seemed to behave normal. then i removed the block above the trapped chests and it fixed it but now i have to redisign the hole system.

Picture 1: I put the item in the top chest

Picture 2: The item is stuck in the hopper

Picture 3/4: I remove the block on top of the target chest
Picture 5: The item passed its now stuck in the second hopper

Picture 6/7: I again remove the block on top of the target chest

Picture 8: I get an output

Tried this again in 1.10 and the item just flew to the last chest.
(But comparator didnt update :o)
