Need help plz: Issues after installing Digi-Tails

[72Z/28]

I have been I having issues after installing Digi-Tails parking light kit on my 68 camaro.

I have replaced both of my flashers with LED Electronic no load flashers for both turn signals and hazards because also have LED tail lights.

Had to use polarity reverse adapter for my turn signal flasher only. Did not need to reverse polarity for my Hazards flashers
Now to the problem:

My hazards or 4 way flashers freeze when I apply the brakes. When I get my foot of the brake pedal, it continues flashing.

I do not any issue with turning signals and applying the brakes.

So could somebody chime in please to identify the reason why the 4 way hazards/ flasher stops working when applying brakes.
