Movement Left Or Right

Hello everybody !
Im making my new game but im having some problems.

I want enemie to move only in right but sometimes the enemie moves left can anyone tell me how to fix that problem and to dont care more about this?

 

if you are making enemies move on path make sure it is set as single mode instead of loop or ping pong

 

Thanks but can you tell me how to fix that , what i have to do to make it move only in left or right ?

 

Are you using paths? or wake up distance with a transform?

 

Linear movement i type any number for move object but sometimes my object moves in left and sometimev moves in right idk what is that

 

@gashigashi I don't know if that helps you Please find the attached video.
