Multi-line function breaks /function call

I'm running MCreator 2021.2 (Build 36710) Java Edition and having some weird issues with functions. 

When I add a single command to the function/file it will show up when in-game using /function and hit tab to see the list.  However, if I add more than 1 command to it (on separate rows as documented), the entire function no longer is visible with the /function command and isn't executable.  The tabbing after /function shows an error instead of showing me my function.  I've tried adding execute as @s before it and still nothing.

Anyone else see this or know if there is something else needed that isn't documented?  Thanks! -Steve
