1.12 @s issue

So, when i use command blocks in Minecraft 1.12. I type the following command: "/tp @s 0.0 10 0.0".
i power the command block and then it does nothing.
i see the report. It Says: Cannot Find Entity "@s".
It says @s targets the executing entity.
I was the executing entity and it didn't tp me.
Please fix this Issue
BTW my IGN [in game name] is: TechnoMojoo
