Adding a new row in Hero Grid Channel

Hi everyone, 

I hope you're all well 🙂

This weekend I finally started to put together my first ROKU channel and are using the Hero Grid Channel template/code located here:

I'm trying to make all the thumbnails under the main row the same generic size (i.e.; not poster) - I've changed the dimensions for this row and it now shows the correct dimensions, but, under it has created a gap about the same size as the other rows?

All very odd and I reckon I must be doing something obviously wrong.

If anyone has any tips, then I would love to know what I could do to fix this 🙂

I'm not actually at my machine that I code at at the moment, however, I'm more than happy to send over on here script/code if anyone wants to have a look to see what I maybe doing wrong (hopefully its simple/obvious to those that know):

The code from GitHub is:

Many thanks,
Chris 🙂

I'm going to look into another basic channel template to see if I get better results. I'll post if I find anything.

If your rowHeights and rowItemSize don't change, I think you only have to add them as far as the differences occur.

So if there's only one row that's larger - then you can streamline your code to
