sometimes when I write the command in the command_block the text turn into #

For example

scoreboard players remove @p[X=~ ,y=~5 ,z=~] point 5

It turn into

#####################

and another example

Scoreboard players remove @p[r=5 ,X=~ ,y=~3 ,z=~] point 5

It turn into

Scoreboard players remove@p[r=5 ,X=~ ,y=~3 ###########
