Whole Grapes

I am preparing to can some grapes from Healthy Canning.

This recipe says that if you have seeded grapes, you need to remove the seeds. I have purchased seedless grapes, but most of them have small seeds. Should I remove the seeds from my seedless grapes? Or is that advice in the recipe more for the seeded grapes with large seeds? TIA!
