Spectacle in Kubuntu 20.04.2: every time I take a screenshot it opens a new instance window. Could the program reuse the same instance?

I'm using Kubuntu 20.04.2 LTS and every time I take a screenshot with Spectacle (version 19.12.3) it opens a new instance window leaving me with multiple windows after a while. Is there a way to make it reuse the same instance and avoid the extra windows? I don't remember this was the behavior before. Thank you.


The solution I found was that I deleted the global print command and added it again, after this every snapshot stays in a single window as intended.
