The app defaults you to try a free subscription to Walmart + when you checkout. If you don't want it, be sure to uncheck the box. It doesn't default to what's available in-store filter while you're in the middle of shopping for a pickup order. It'll be sneaky and put the items you ordered which were unavailable in-store to be picked up, as shipping, so be careful of that, too. If you don't want items shipped, check the bottom of your order.
