Robin Image Optimizer creates faulty links and so drops 404 errors

I uploaded an image called “Haithabu_Fruehlingsmarkt_2019 52.jpg” to the server an it was optimized by RIO. But on the website RIO creates this filename “Haithabu_Fruehlingsmarkt_2019-52-800×569.jpg” and the Image is not shown but creates a 404 Error for it. I looked into the upload folder and it really does not exist. So RIO creates this link but not the corresponding image-file. I created a blog entry with many image galleries and they all are fucked up. Also, if I upload an image directly from Gutenberg to an gallery it will not be optimized automaticly btw.

So I think I can’t use RIO anymore and have to deinstall it to get my site running again.

The page I need help with: [log in to see the link]
