I'm just trying to reference one of my example in my text but it's always labelled with the upper previous counter (here the section number).

My example environment is defined as exmp which are a tcolorbox environment itself. I know that the trouble probably comes from my newtcolorbox definition but I cannot find from where. If you have any idea, please tell me.

I'm working with the pdfLaTex compiler and here is my minimal code:

\documentclass[justified,notoc,numbers]{tufte-handout}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{xcolor}
\usepackage{color}
\usepackage[most]{tcolorbox}

\usepackage{lipsum}

  attach title to upper,

}

  headsep=10mm,
  headheight = 0mm,
  marginparsep=7mm,             % gutter between main text block and margin notes
  marginparwidth=50mm,          % width of margin notes

\lipsum[1]
\end{exmp}

Try to reference to my example counter using \texttt{ref\{EX1\}}: \ref{EX1}

\end{document}

So here the result is

What it give

when what I want is

Thanks a lot.

SOLVED:

The trouble was indeed with my parameters declaration, I need 2 and not 1 parameter. #1 is my option while #2 will be my title. Here is the code of the solution:
