WatchOS background image stretching under table

I a table view in my watch app which I am trying to put an image behind. This is what it looks like in the storyboard:

and this is what I want, but when I run it on the simulator with a number more rows it seems to stretch the background image downward like so:

Any ideas for I might be able to make it not stretch and be static in the background (not scroll with the table)?

Thanks in advance

My only thought would be to add the table to a group and set the background image of the group to whatever image you want. However, the image will be behind the table and not in front of it.
