Cannot get score of entity

Using this command:

/execute @e[score_PkmnID_min=2] ~ ~ ~ tellraw @a {text:"",extra:[{score:{name:"*",objective:"PkmnID"}}]}

I get an output of three question marks, one from each of the mobs with an PkmnID score at two or above. Using the * should make it target the entity that runs the command (the entity) and it should then display the PkmnID score of it, not question marks.
