bug: slick slider rendering slide item for Null values !

[redwanul10]

Recently I'm using slick slider I noticed that if I return null from a component the slider is still showing slide item for the null value. let me share an example let's say i have 4 items in a list I'm returning null for the first 2 items so slider should show only 2 items since null is not a valid value/component but it's showing 4 items with 2 empty slides ! is this expected behaviour in slick slider ?

I also tried the same example using Owl carousel which is showing expected results.

Having the same problem, even if there is no item or null react-slick slider component is adding an empty div for null values
