The commands that i used are

/scoreboard objectives add health health

/scoreboard objectives setdisplay sidebar health

/scoreboard players add @a health <points> (please note that i did not set the points variable because it is a read only objective

The output on all commands(in order) was:

1. [07:27:14] Created new objective [health]

2.[07:27:22] Set display slot sidebar to show objective health

3.[07:27:46] ... @a health<–[HERE]

if i do define a score this is what the output reads:

[07:42:17] Scoreboard objective 'health' is read-only

I believe That this is a bug pls fix because i need a few scoreboards to display
