HP Prime G2 and CAS cosmetics (cube root)

[F22Dead]

Hello, I am new to this forum.
I got a new HP Prime G2. Nice machine!
Already updated it to SW version: 2.1.14603 (2021 12 02)
(HW ver. D; CAS v1.5.0; OS V2.060.650)

I have a question about CAS display output.
In the HOME settings I have "Textbook Display" and "Intelligent Math" checked.
In CAS, Square Roots display very nice in input and output,
but cube roots display as fractions (i.e. 1/3).

The question is if this is working as designed (written),
or if am I doing something wrong, missing an option/combination.
To be more clear, I can enter a cube root (Shift+Xy) where the "3" is left of the radical sign, but the output is alwasy in fraction format.

Comments and/or suggestions would be very much appreciated.
