Column Not Displaying on Mobile View

Hi. I have a layout with 3 columns. The columns work ok in desktop and tablet view but on mobile view one of the columns is missing. Would anyone know why this is happening?

Here is the link to the test site.

I answered my own question. The solution was to set a height in pixels on the slider mask and then a percentage height on the block column.

Hi @PHforum and welcome, you can also type manually Auto to Mask height

Thank you!. That is much better.
