Some images are no longer loaded

I discovered this plugin and I am actually very happy.
Unfortunately, I had to notice that in some posts the images are no longer loaded after activation.

The links of the images changes:

Before:https://www.test.dinkelliebe.de/wp-content/uploads/Erdnussbutter-Apfel-Kuchen-4.jpg

After: https://www.test.dinkelliebe.de/wp-content/uploads/Erdnussbuttera??Apfela??Kuchen-4.jpg

Some other examples:

I hope you can help me.
