The new "execute" command is not applied in "mcfunction" files. 

I have tested both the new and old "execute" commands, and only the old one functioned. 

I made "test.mcfunction", and functioned it in the game. I uploaded the content of "test.mcfunction" and what happened when I functioned as images/videos below. I have tried changing the "version" of the "manifest" file of the behavior pack, but it did not work neither. 

Since it is a fatal bug for players creating behavior packs, I beg for a quick respond. 

By the way, I'm Japanese, so please forgive my poor English
