I have made a test:

Apparently the percentage output of progress is not shown on your system.

Did you set the variable `GRASS_MESSAGE_FORMAT` to anything specific?

Comment (by jidanni):

I can't test for the next few months.
All I remember is that I used an emacs shell window, or M-x compile.
So many of interactive things that depend on terminals and CR LF stuff
will look different.

Comment:

As per https://grass.osgeo.org/grass78/manuals/variables.html, you can set
for your case

`GRASS_MESSAGE_FORMAT=plain` - sets percentage output and message
formatting style to ASCII output without rewinding control characters.

I'll close for now, feel free to reopen as needed with more tests.
