Jacobi elliptic function

[salvomic]

With G2 Software version 2.1.14433 (2020 01 21) both in CAS and Home, if ‹number format› in Home settings is set "Standard" and Angular mode is set to "RAD" I'm trying this input for my program:

Code:

jacobi_fn(asin(1),0.4^2)

the input become

Code:

jacobi_fn(ASIN(1),0.4^2)

and the return is a matrix where the second elements of the two rows present a wrong char instead of the numbers ("⌷"), maybe an ellipsis (...)?.
See the above attachment.

If I set other format, like "Float 9" or another angular mode ("DEG" or GRAD), also with "Standard" setting the matrix shows ok.

Is it a bug or a problem here? Am I missing something?

Thanks for help.

EDIT 1: if I input acos(1) instead of asin(1) the output is ok (but also that function become ACOS(1) in the display) and also with "Standard" format, however not if I put a number or e.g. π/2.

EDIT 2: the view is ok if I traspose the generated matrix but not if I put manually in the input line the same matrix (not transposed)

EDIT 3: in iOS I get two different output: in Home the "⌷" become an ellipsis sign (...); in CAS I get an error "Error in input": why?
