List of figures in multicol environment

List of figures in multicol environment

I wish to reduce the spacing between items in my list of figures, the list of figures is in a multicol environment.
The following command:
\makeatletter
    \let\l@figureOLD \l@figure
    \renewcommand{\l@figure}{\vspace*{-5pt}\l@figureOLD}
    \let\l@table\l@figure
\makeatother
achieves the reduction in spacing, however, for some reason, it is forcing all the entries in the first column, without column balancing.
If I comment out the above, the column balancing / breaking works as expected.
