Hello, I'm attempting to reproduce this problem. I've tried all of the image update strategies and could not reproduce this bug.

Can you please provide the exact annotations used for your application that is having this problem.

Looking at the relevant part https://github.com/argoproj-labs/argocd-image-updater/blob/release-0.16/pkg/argocd/argocd.go#L233, it is parsing the image-list annotation value using comma as the separator. I think using comma with or without spaces as separator in image-list annotation should all work.
