Mark on Hit Curses get overwritten by lower lvl curse

It is my understanding that lower lvl curses cannot override higher lvl curses.

Tried both marks at different levels
Mark on hit support + Poachers mark lvl 2 + lifetap
Mark on hit support + Snipers mark lvl 20 + lifetap

The mark gets overriden by Enfeeble + Elemenetal weakness curse on hit gloves. Which should be lvl 1 curse on hit

Character has +1 to curses. So assuming mechanics work, then higher lvl mark should be applied, followed by the next curse in descending order, Elemental weakness.

This is not the case, Elemental Weakness + Enfeeble overrides the Mark.
