Editing actions within a droplet?

I have a droplet that resizes and saves photos to a specific droplets folder. I just upgraded to Mojave and when I drop an image on it for resizing it now tells me

"Could not complete the action since the destination folder does not exist."

I haven't changed anything and the destination folder DOES exist. Not sure how to go into the droplet and choose the folder again (as I think it doesn't have the path anymore).

I tried deleting the droplet and uploading a new saved version of the same one from an external drive but it produces the same error.

I have one other droplet with all the same actions just for a different final size and it still works.
