Thank you so much for your help, that did work! Unfortunately, it also caused an issue on the main store page, where it broke the side by side columns. The item categories were moved above the list of items rather than being to the left of them.

I've left the code in my site so you can see it here https://www.sunkentreasureaquatics.com/plants
Is there any way to fix this? Thank you.
Also, do you have a donate button? Happy to throw some cash your way for the help!
