Overriding some MDB SCSS Variables doesn't impact compo

Expected behavior Overriding $btn-padding-y-basic and $btn-padding-x-basic variables impacts buttons created as mdbBtn component. There is no custom scss necessary to fix button paddings.

Actual behavior: The variables are useless, the component is always created with the default paddings even if overwritten correctly (other bootstrap variable overwrites work fine). Button Styles have to be defined manually.

SCSS Imports:

// Define core variables and override variables (Bootstrap & MDB)
@import "variables";

//Import Bootstrap & MDB 
@import "~ng-uikit-pro-standard/assets/scss/bootstrap/bootstrap.scss";
@import "~ng-uikit-pro-standard/assets/scss/mdb.scss";

@import "utilities";
@import "custom";

Variable Overwrite:

//Bootstrap Button Variables
$btn-font-size:               $font-size-base * 0.8;
$btn-padding-y:               .65rem;
$btn-padding-x:               1.75rem;

$btn-font-size-sm:            $font-size-base * 0.65;
$btn-padding-y-sm:            .5rem;
$btn-padding-x-sm:            1.5rem;

$btn-font-size-lg:            $font-size-base * 0.95;
$btn-padding-y-lg:            .8rem;
$btn-padding-x-lg:            2rem;

//MDB Button Variables
$btn-margin-basic:    0px 0.375rem;
$btn-font-size-basic: $font-size-base * 0.8;
$btn-padding-y-basic: $btn-padding-y;
$btn-padding-x-basic: $btn-padding-x;

$btn-font-size-small: $font-size-base * 0.65;
$btn-padding-y-small: $btn-padding-y-sm;
$btn-padding-x-small: $btn-padding-y-lg;

$btn-font-size-large: $font-size-base * 0.95;
$btn-padding-y-large: $btn-padding-y-lg;
$btn-padding-x-large: $btn-padding-x-lg;

Button creation

<button id="{{id}}" type="{{type}}" mdbBtn mdbWavesEffect [attr.aria-label]="text"
  [ngClass]="[customClasses, isFlat ? 'btn-flat-' + actionType : '', isActive ? 'active' : '']"
  [disabled]="isDisabled" [color]="actionType" [flat]="isFlat" [size]="size" 
  [block]="displayBlock" (click)="notifiyButtonClicked()" ></button>

Behaviour: Button still rendered with default paddings (x 0.84rem, y 2.14rem), following SCSS is necessary to manually fix:

button, a, div, span {
  &.btn {
    margin: $btn-margin-basic;
    @include button-size($btn-padding-y, $btn-padding-x, $btn-font-size);
  }
}

It would be a huge help if it scss variable overrides would impact mdb components without any custom SCSS.
