Slider acting up until reseting viewport

Hi :smiley: So while building a portfolio for myself I tried to add a slider but for some reason it doesnt change to the next slide correctly, it kinda stops halfway. Only solution I’ve found is to change or reset the viewport size but this only works until the page is loaded again.
Why is this happening? what am I doing wrong? Is it a bug?
