## Expected behavior
This is what occurs when I don't have `alias lsd="lsd -lAF --blocks=permission,size,date,name --date=relative --total-size --group-dirs first"` and `alias ls="lsd -lAF --blocks=permission,size,date,name --date=relative --total-size --group-dirs first"` set in my `.bashrc`.

## Actual behavior
With both aliases set in `.bashrc`:

Is it because I have lsd set as alias before the ls alias?

Start by reproducing the behavior with repeated --blocks options and compare the output with the single-option and alias examples in the report. Trace the CLI parsing and option-handling entry points to determine which value is retained. Done means the last --blocks option is used consistently, with regression coverage for repeated options.
