Not showing products in search

Hello,
I just installed your plugin and everything loaded correctly.
I was able to search for a product, add it to the cart and check our successfully.
I went to create a new order and now when I type in a product or SKU in the search bar it says “No Product Found” for everything.
I have tried deactivating, deleting and reinstalling the plugin and it still will not work.
Please let me know if you require a staging site.
