Can't do /tp instead of /teleport.

I am needing to create a command block contraption that involves running /tp in a repeating command block. I've done this before, however I noticed that now it automatically assumes I mean /teleport. I've been typing /tp and was trying to move an entity upwards with /tp @e ~ ~1 ~. However, no matter what I do it always teleports it to one block above the command block, even if I just type /tp. In the chat /tp works however in the command block it becomes /teleport.
