Help please! Fancy gloss thermal topcoats

I recently got a bunch of Fancy gloss thermal top coats in red, black, blue, purple and other colors. While I love them, it has been distorting the color and finish of my nail polishes. For eg: on a regular polish, the purple polish changes the color of the polish underneath. Similarly on top of holographic polish or a flaky or shiny polish such as Mooncat House of Hades, it completely changes the finish of the polish to a dull lifeless satin finish, clearly minimizing all the shine.

All the thermal top coat lovers- What am I doing wrong? Do I need a water based top coat on top of the polish and then apply the thermal top coat? Please help!
