Wrong behavior of symbolic number creation in R2022a

In R2022a, when I tried to create a symbolic number, I got this output:
>> sym(1/3)
ans =
0.3333
The document ( https://www.mathworks.com/help/symbolic/create-symbolic-numbers-variables-and-expressions.html ) says it works as below:
>> sym(1/3)
1/3
Below is the version I am using:
Symbolic Math Toolbox Version 9.1 (R2022a)

Did you change your symbolic preferences without realizing it?
sympref('FloatingPointOutput',true);
x = sym(1/3)
sympref('FloatingPointOutput', false);
y = sym(1/3)
sympref('FloatingPointOutput', 'default');
z = sym(1/3)
whatIsFPOSetTo = sympref('FloatingPointOutput') % Default is false
