Scoreboard 'belowname' display disappears under specific conditions

The scoreboard display below the player's name (in the 'belowname' slot) becomes invisible for the player who executes a specific command sequence, even though the score for 'belowname' objective has not been reset.

Steps to Reproduce:

1. Create two scoreboard objectives:

/scoreboard objectives add test01 dummy

/scoreboard objectives add test02 dummy

1. Set test01 to be displayed in the sidebar or list, and test02 in the 'belowname' slot:

/scoreboard objectives setdisplay sidebar test01

/scoreboard objectives setdisplay belowname test02
(Alternatively, use list instead of sidebar)

1. Set the scores for yourself (@s) for both objectives:

/scoreboard players set @s test01 10

/scoreboard players set @s test02 20

1. Reset your own score for test01 (the objective displayed in sidebar/list):

/scoreboard players reset @s test01

1. Have another player check your 'belowname' score.

Expected Result:

Your 'belowname' should still display the score of 20.

Actual Result:

The score in the 'belowname' slot disappears/is not displayed only for the player who executed the reset command (i.e., your own belowname score is invisible to others).

Additional Information:

• Setting the score for test01 again (Step 3), or clearing the 'belowname' display (/scoreboard objectives setdisplay belowname) and then setting test02 again (Step 2), makes the 'belowname' score reappear.

• The issue seems to be triggered specifically by resetting the score of an objective that is currently displayed in another slot (sidebar or list).

• I have checked it on Windows and iOS.
