W3 Total Cache & Bogo compatibility problem

Hey,

we are using the plugins W3 Total Cache and Bogo (for multilingual pages) on our site https://academy-of-fine-art.com/.

The W3 Total Cache works on the default language site https://academy-of-fine-art.com/ without problems, the css and js are all minfied in one file. But on the german pages https://academy-of-fine-art.com/de/ the plugin don’t minify the files.

How can I fix this? Does anyone have the same problem?

Best regards
Marvin
