Bug with Widgets | WordPress.org

Hi there!
We’ve found a little but annoying bug with converted images in widgets. Every time as we editing and after saving a widget with images inside it – plugins adds extra “-optimized” word to image name. So for example we can have 3 “-optimized” words for one image path and of course it breaks showing of images
Here an example https://ibb.co/7b6HqJC
Is it smth that I can do to fix or prevent it? thanks!
