Inconsistent execution with dropdown boxes

I’m new to katalon studio and software testing as a whole so I have little to no idea whats going on when a bunch of error comes in.

So anyway I’m having trouble with dropdown boxes. Sometimes it works sometimes it can’t see the element for some reason. Here are the list of errors.

I’m also having trouble clicking the 2nd next button. On my first page I was able to click it but on the 2nd page katalon studio just can’t see the element even if I used Scroll to Element or Scroll to Position

//2nd next button not being seen
