copy bug

[peacecalc]

Hello all,

I'm a newbee with the prime calc. Maybe in former times that behavier is reported, so don't be shy to delete that thread, if this are old marshmallows.
I use the real machine G2 with the newest firmware.

First HOME modus:
In pic 1 you see a the expression: (5^(1/3))^2 and I want to copy the expression to the input line.
In pic 2 you see what I get: (5^(1/3)^2) and that is completely different.
I tried that with floats, too (5.^(1./3.))^2. After keying in, it is displayed like in pic 1 and the resulting behavier is same like with integers.
But it becomes more strange. In pic 1 you see the expression on the left and right side of the display,
if you copy the expression from the left side it works, but from the right side it doesn't??? So what?

I try this in CAS Modus:
In pic 3 you see the same situation as in pic 1.
In pic 4 I get the right thing after copying.

greetings from an astonished user....
