A LaTeX package is used to update marks in boxes.
You can use \usepackage[minipage,multicol,tcolorbox]{updatemarks} in the preamble
of your document so that marks in these environments can be found by LaTeX.
You are able to use \ExtractMarks or \ExtractSplitMarks to save marks and
use \UpdateMarks to reinsert marks. Read the documentation for more details.
