(no worries about where the post goes, @dianne.dietrich! I have indeed moved this thread to the Support section so that it can be referred to later, but it is simple to do that on my end)
We’re investigating this and I will get back ASAP. We have had caching concerns before so it may be something with the Software resource’s metadata still showing in the UI though the resource itself is gone - I’ll check in that 1) Software resources are being deleted properly and 2) the front-end’s cache is resetting immediately to reflect the deletion. Can I confirm that you are trying to delete as an “Admin”-level user?
In the meantime - giving a new name to the resource can help with troubleshooting a problem like this, yes, though you can also get the resource UUID by clicking on the title and going to the Software resource’s Details page. That can help confirm whether you are truly looking at the same resource or not. (If you receive an error trying to go to the Details page, that would be further confirmation that the resource itself is gone and the card still being available is the problem/artifact)
